How to choose and benefits of partnership with a good contractor to develop your project?

“We specialize in providing professional software development services to clients.” Such a statement will appeal to any potential client, but alas, any applicant-contractor positions himself as a professional. Indeed, if you honestly admit to being unprofessional, then you will not be allowed to come close to any project. But how can a client, who usually does not understand the intricacies of software development, be sure that the contractor really knows his business? If there was a simple answer to this question, then a lot of the money that is now spent on projects that are doomed to failure from day one could be saved. 

This article offers the simplest test of professionalism, comparable to the “litmus test”: it lists the minimum set of skills inherent in a good developer, such as Svitla Systems. An inexperienced client should put such questions to the contractor – and he has the right to count on meaningful answers. I must say right away: I compiled this list with the best of intentions. Programs can be developed with a partial or complete absence of these skills, and this can be quite a professional development. On the other hand, even the presence of all of the above does not guarantee the triumphant completion of the project. So let’s say you’re a client looking for a suitable software development contractor. For you, it can be both a freelancer and a company. 

You can simply arm yourself with this list and ask the candidate all the questions from it in order. Listen to what they have to say and ask them to demonstrate certain skills in practice. At first, you are unlikely to be able to distinguish a brilliant implementation from a trivial one, but gradually you will learn to do it. The bottom line is this: if a developer can easily demonstrate a particular skill, then most likely he is really good at it.

Minimum Skills

The list of skills is arranged in ascending order of their direct impact on the quality of development. The idea of ​​quality counts on three levels: from your (customer’s) point of view, from the point of view of the end user, and from the point of view of the next developer who gets the source code from the first developer.

Source code management system

This technique has a number of different names: source code management (SCM), version control system (RCS or VCS). It is used to track any changes that are made to the code over time. Using such a mechanism, the developer will be able to know exactly what change was made to the code and when, in which version it happened and who made it. Later, such a change can even be undone. If your interlocutor says that he has experience with specific version control tools – for example, Git, Subversion, Perforce or Mercurial, then this issue can be considered resolved. Have a contractor demonstrate a typical sync-edit-edit cycle and try to understand what he’s telling you. Most developers like to brag about their mastery of version control systems.

Task Tracking

The Issue Tracker (and also the Bug Tracker) is a tool that saves all the requests, bug reports, feature requests, and complaints you make. It can be compared to a trouble ticket help system. The issue tracking system provides the developer with a kind of “action plan” and acts as an objective documentation of your communication with the developer. If you can’t directly access the site’s issue tracking system, have the candidate demonstrate a typical scenario, such as filing a bug report. At a minimum, the developer should provide you with a list of resolved issues for each version of your software.

Continuous Integration

This is a relatively new tool, but it has significant potential. It can also be called an “application build server” (build server). There is also talk of a “nightly build”. We assume that the build of your project will be automated whenever possible. In the case of continuous integration, a new build occurs after each submission of a new portion of the source code to the version control system (we talked about it in the first paragraph of our list). Ask a developer to demonstrate what happens automatically after submitting code to source control. Ask the candidate about the “build time” of your project (or other projects). Build time is the period it takes to get a new version that you can test. If the build time is quite short (say, a few minutes) – ask for a small change to the project and wait for the result. It is possible that your developer will touch not only the topic of “continuous integration”, but also “continuous deployment”. 

Questions will pop up related to “staging files”, “build queue”, “test installation” (test installation), etc. That is great! Give him the opportunity to demonstrate “continuous deployment” in practice. You will probably be impressed and the developer will get another chance to trump for you.. e. That’s great! Give him the opportunity to demonstrate “continuous deployment” in practice. You will probably be impressed and the developer will get another chance to trump for you.. e. That’s great! Give him the opportunity to demonstrate “continuous deployment” in practice. You will probably be impressed and the developer will get another chance to trump for you..

Verification (aka testing)

“Will the source code contain automated tests?” Oh, this is a delicate issue. In our business, the expected value of any automated tests is still approaching absolute zero. But, if in response to this question the candidate simply looks at you in bewilderment, this is a bad sign. In the case of a meaningful answer, it is not so important whether “unit tests”, “integration tests”, or even “acceptance tests” are mentioned. More importantly, let the candidate demonstrate to you the implementation of automated tests in your (or similar to your) project. Make sure that the continuous integration server (more about it in the third paragraph) really runs automated tests, and at each build. 

Thus, if any component, supported by tests, fails, you will immediately know about it, and you will not have to deal with errors, which appear again and again in each subsequent version (such a symptom is called “regression”). Perhaps your developer will be a true testing enthusiast. And let every hour of his work cost a lot of money – do not doubt that the money for testing is not spent in vain. Think of this as a safeguard against any unexpected future behavior of your program. 

During development, the tests themselves are likely to be invisible, since they are used internally. Ask the developer to talk about how they organize test reporting. Perhaps a “test coverage” report is being compiled to accompany the list of tasks (such a list is discussed in the second paragraph)? If a specialist claims to practice “test-driven development” – you can be sure that that he tries to conduct the most detailed tests. Let him show you the merits of this approach and model the implementation cycle of a small change in your project. Perhaps this will convince you of the usefulness of such reinsurance.

Project documentation

All software projects, except for the most elementary ones, contain such a mass of details that a person is simply not able to remember them all, and sooner or later he forgets something. Your developer should have some hands-on experience with storing project information, not just “in code” and “in the issue tracker”. A popular way to implement this requirement is to document the project in a wiki form – it is in this form that the well-known Wikipedia is written. Consider using an online text editor with structured information. If you don’t have access to the documentation tool itself, ask the developer to demonstrate it in practice. Ask for an extract from your project’s documentation, for example in PDF or HTML format. Do not find fault with the aesthetic aspects of the document, its main qualities should be – the convenience and ease of finding the right information. In the end, even handwritten documentation will do, as long as it’s in order and kept in one specific place.

Conventions in source code

Almost any source code is machine-readable. But there are such code samples that are completely unreadable for a fellow programmer, and even for the author himself. Ask the developer about what code formatting rules he uses. Perhaps he will actually present you with written rules that actually apply when creating code. Most programming languages ​​have tools that allow you to check formatting against certain rules. These programs are called “code inspection tools” and are ideal for working with a continuous integration server (see third point). However, some aspects of the readability of source code cannot be checked algorithmically, such as the choice of names or the clarity of concepts. Good developers review their code regularly, critically discussing it with colleagues and suggesting optimization options. And a good client openly indicates the need for code review, even if he himself is not going to participate in it. In the long run, you will soon see for yourself how much this improves the quality of programs.

Participation in the life of the community

Software development is a fast-growing field of activity in which life-changing discoveries occur every now and then – no less than once a year or two. A single developer cannot keep track of the development of all the constantly changing tools, phenomena and opportunities in the field of his professional activity. You have to rely on the experience of a community of colleagues and like-minded people, as well as experienced experts who are ready to share their knowledge. Ask the developer how they interact with the peer community. What (technical) books has he recently read? What books have been studied by the entire development team? You, as a client, may not be able to immediately assess how valuable the books named by the developer are, but this is not the most important thing. As with tests, the list of books read by the average programmer may not be very long. It is important that the development team is sufficiently cohesive and has a common base of technical knowledge gleaned from specialized literature. But the matter is not limited to books. After all, printed books just can’t keep up with the development of the industry! Ask about the technical conferences the candidate attends and whether they are in user groups to discuss the programming language used in your project. How is collaboration organized? Does the developer like to share his experience and findings? By the way, for this it is enough just to maintain your own blog (for example, the one you are reading now). Ask a programmer to show you his blog. How many articles did he publish in a certain period of time, what is the response to them? May be, Is your candidate writing articles for a specialty magazine or even working on a book? And now it will be possible to ask other developers for their opinion about the published materials. Perhaps you have found a true professional – it remains only to congratulate you!

But that’s not all, not all…

This list does not exhaust all the skills, concepts and tools that a good specialist should be able to work with. This is just a minimal set that can and should be supplemented and improved. There are whole sets of skills, such as “clean code development” – it’s impossible to mention them all. Ask about what is interesting to the developer himself. Hopefully, his appropriate bluster and professional slang will quickly convince you that you really are dealing with a professional. And you shouldn’t be satisfied with less.


Developing a Supply Chain Strategy

Supply chain strategy occupies an important place in an organization’s strategic planning system. Let’s break down the types of supply chain strategies in detail according to their level in the strategic planning system.


The main types of supply chain strategies


1. Corporate strategy is a general plan of management of the organization, representing a set of decisions concerning the choice of branches and geographical regions of activity of the organization, acquisition or exit from this or that business, distribution of key resources between various spheres of activity, etc. We can say that corporate strategy reflects decisions on the choice of strategic business areas of the organization. In essence, corporate strategy solves the investor’s problem – how to distribute investments in assets in order to maximize the economic return on them. When developing corporate strategy, a key role is played by understanding the trends in markets and the economy as a whole.


2. Business strategy is a plan for the development of a separate area of the organization. For each area (direction) of the organization formulates its own strategy. It defines the mission and objectives of the direction, as well as ways and means of achieving competitiveness of the relevant products or services. Business strategy details the corporate strategy for a particular business area and describes the strategic plan for its development. Business strategy, in turn, contains functional strategies that describe certain aspects of business strategy.


3. Functional strategy is a set of activities and programs of individual functional areas and departments of the organization. Each functional area within the organization (marketing, production, finance, product and service design and development) determines how it contributes to the strategic goals of the organization. The functional strategy is the basis for action within the business. In particular, the marketing strategy is focused on the choice and justification of the product portfolio of the organization and the target markets, financial strategy – the choice of sources of financing the activities of the organization and assessing the cost of capital, the strategy of development and development of products and services – the creation and preparation for launching new products and developing new technologies. Operational strategy should help to implement the marketing strategy and the strategy of design and development of new products, taking into account the limitations dictated by the financial strategy.


4. Operational strategy, therefore, is one of the functional strategies of the organization. It deals with such components as managing production capacity, managing supply chain position and relationships with counterparties in the supply chain, managing production and management technology, and managing organizational development and competencies in the organization.


Supply chain strategy, in turn, can be presented as one of the components of operational strategy, dealing with the management of the production capacity of supply chain links, as well as the management of the position and interaction of links in the supply chain among themselves.


Production capacity is the maximum possible output of products or services by an organization over a planned period. For example, the production of tons of products per year, pieces of products per month, hours of services per quarter, etc.


Decisions on productive capacity of the organization can be divided into two groups: decisions on configuration of productive capacity and decisions on development of productive capacity.


When managing production capacity at the strategic level, the following decisions on its configuration are made:


  1. The overall level of capacity (including reserve capacity, important for enterprise flexibility, process speed, and cost levels);
  2. Distribution of capacity across production and/or service sites (i.e. the extent to which operations are centralized or distributed, and whether vertical integration and cooperative supply chains have been established);
  3. The specialization of production and service sites in the production of the relevant product group or type of services rendered;
  4. physical location of the sites in the world, country or region.


Decisions on the development of production capacity reflect three main moments:


  • The moment of change in production capacity;
  • the scale of incremental change in production capacity;
  • The time it takes to change production capacity.


In terms of the moment of change in production capacity, there are two main strategic approaches:


  • capacity outpaces demand, that is, capacity is brought on line ahead of projected demand for products/services; capacity “catches up” with demand, that is, capacity is brought on line based on customer orders received that regularly exceed available capacity;
  • the imbalance between the available capacity and the demand for products is smoothed with the help of formed stocks (stocks are formed during the period when the capacity exceeds the demand and are consumed during the period when the demand exceeds the capacity).


Each of these approaches has its own advantages and disadvantages.


The scale of capacity change implies two main approaches:


  • changing capacity in large steps, commissioning large facilities;
  • smooth change of capacity through commissioning of small capacity units, in fact – the strategy of following capacity as closely as possible to the value of demand for products/services.
  • The time required to change production capacity must be taken into account when choosing the size of the planning horizon when forming strategic plans.

Decisions to manage an enterprise’s position in the supply chain


They mean the choice by an enterprise of its direct control zone in the supply chain. And this zone of control (links of a chain of deliveries which the organization owns) can be located at the beginning of a chain of deliveries (the first stages – extraction and primary processing of raw materials), in the middle or at the very end (retail trade). A variant with full vertical integration is also possible, when the organization controls absolutely all links in the supply chain: from raw material extraction to the end consumer, though such a wide coverage is not common in practice. Accordingly, the enterprise chooses in which of the links (in which of the links) of a chain of deliveries to the greatest degree provides stable competitiveness.


When selecting a position in the supply chain, the enterprise must also decide on the need to differentiate its supply chain management depending on the market it serves. Different markets may have different requirements in terms of a set of competitiveness factors. It is quite possible to build several supply chains independent from each other, focused on different key success factors (speed of delivery, acceptable costs, product quality, etc.)

Supply chain configuration

The enterprise chooses its location in the supply chain – which links in the supply chain it will directly control through ownership relationships, and which neighboring links in the supply chain it will need to cooperate with. At the same time, there is a link (enterprise) in each supply chain that has the greatest influence on the configuration and organization of the supply chain. In international literature, such an enterprise is sometimes referred to as a channel master. Accordingly, the question of what role the enterprise will play in the supply chain, whether it will set the tone for supply chain practices or be in a subordinate position, following the rules established for the supply chain by its most influential link, is not unimportant for each enterprise in the supply chain.


Another important point is to decide how to respond to those dynamic forces that affect the enterprise in the supply chain (changes in customer demand, material flow dynamics, changes in the balance of power in the supply chain, information flow dynamics), i.e. how the enterprise strategically aligns its supply chain policy in terms of managing demand, inventory, purchasing, production, distribution, etc.


There are two main groups of decisions in the configuration of supply chains: decisions on the management of its position in the supply chain and decisions on the choice of the type of relationships with counterparties (suppliers, customers) in the supply chain.

The choice of the type of relationships with neighbors in the supply chain

This is no less important than the positioning of the company in the supply chain. Here we are talking about strategic decisions such as:


  • choosing a strategy by number of counterparties (e.g., suppliers) – whether to choose a strategy of multiple sources of supply or a single source of supply even when alternative sources are available;
  • choice of type of relationship, which should be sought in interaction with counterparties. The range of relationship types can cover partnerships or even alliances, on the one hand, and the cultivation of fierce competition between suppliers for orders of the organization, on the other hand. When there is a partnership with a counterparty, the organization explores options for its suppliers in order to ensure a more reliable resource base in the long term.


Ultimately, the organization’s task in terms of supply chain strategy development is to create such a configuration of the supply chain that would support the achievement and retention of the target values of competitiveness factors. To this end, in the areas of strategic decision-making (production capacity and supply chain configuration management), the organization decides on the composition of necessary tangible and intangible resources, as well as the composition and properties of operational processes. Resources and processes together form the so-called operational capabilities of the enterprise. The development of an enterprise’s operational capabilities is one of the main objectives of strategic supply chain management.

How to Calculate Variance – Definition, Formula, and Calculation

The variance is widely used in statistics and mathematics. In statistics, this term is frequently used to calculate the spread of the data from the expected value. It measures the typical distance of the data values in the same units such as meter squares.

There is another term that is more stable to measure the spread of data is the standard deviation. It has the unit’s time and meter. In this lesson, we will discuss the variance in descriptive statistics along with its definition, formula, and calculations.

Variance – introduction

In descriptive statistics, a term that is the average of the squared deviation (square of the difference of the data values from the expected value) from the mean is known as the variance. It is widely used to measure the variability in the distribution of data values.

It is expressed in larger units such as m2 (square meters or meter squares). It is generally used to represent how much variation in the data set there from the expected value. The zero value of the variance indicates that all the values are identical in the data set.

It is denoted by “σ2” or “s2” and is calculated by subtracting the expected value from the data value and taking the square of the deviation and dividing it by the total number of observations.

Types of variance

Variance used two kinds of data sets one is a sample and the other is a population, on the basis of these sets the variance has two types

Population variance & sample variance

In this section, we will discuss the types of variance briefly.

1.  Population variance

Population variance is that type of variance in which the population data set is taken. The population is the measure of all the data such as people in a city or girls in a country. Hence the measure of the spread of the whole data set from the expected value indicates the population variance.

For the calculation of population variance, you have to calculate the quotient of the statistical sum of squares and the total number of data values. It is denoted by “σ2”. The measure of the expected value in population variance is denoted by “μ”.

2.  Sample variance

Sample variance is that type of variance in which the sample (random) data set is taken. The sample is the measure of random data from the whole such as people in a school in a city or girls in a class of a high school. Hence the measure of the spread of sample (random) data set from the expected value indicates the sample variance.

For the calculation of sample variance, you have to calculate the quotient of the statistical sum of squares and the total number of data values minus one. It is denoted by “s2”. The measure of the expected value in sample variance is denoted by “”.

Formulas of the variance

The formula for the population variance is:

σ2 = ∑ (yi – μ)2/N

The formula for the sample variance is:

s2 = ∑ (yiȳ)2/N -1

In the above formulas of the variance,

  • σ2 and s2 are the notations of population and sample variances respectively.
  • Yi is the set of the data values.
  • N is the total number data value.
  • μ & ȳ are the populations mean and sample means respectively.
  • ∑ (yi – μ)2 & ∑ (yi – ȳ)2 are the statistical sum of squares.

A variance calculator can be used to solve the variance problems according to the above formulas of variance.

How to calculate the variance?

Let us take some examples to understand how to calculate the variance.

Example 1: For population variance

Evaluate the population variance if the given data set is:

10, 15, 20, 22, 25, 28


Step 1: First of all, calculate the population means of the given data set.

Sum of population values = 10 + 15 + 20 + 22 + 25 + 28

Sum of population values = 120

Total number of observation = n = 6

Mean of population data set = μ = 120/20 = 60/10 = 30/5

Mean of population data set = μ = 6

Step 2: Now value the deviation of the data values from the population mean.

y1 – μ = 10 – 20 = -10

y2 – μ = 15 – 20 = -5

y3 – μ = 20 – 20 = 0

y4 – μ = 22 – 20 = 2

y5 – μ = 25 – 20 = 5

y6 – μ = 28 – 20 = 8

Step 3: Now make the above differences by taking the square of each term.

(y1 – μ)2 = (-10)2 = 100

(y2 – μ)2 = (-5)2 = 25

(y3 – μ)2 = (0)2 = 0

(y4 – μ)2 = (2)2 = 4

(y5 – μ)2 = (5)2 = 25

(y6 – μ)2 = (8)2 = 64

Step 4: Now calculate the statistical sum of squares by adding all the above-squared deviations.

∑ (yi – μ)2 = 100 + 25 + 0 + 4 + 25 + 64

∑ (yi – μ)2 = 218

Step 5: Take the quotient of the ∑ (yi – μ)2 (sum of squares) and the total number of observations to calculate the population variance of the given data set.

∑ (yi – μ)2 / N = 218 / 6 = 109/3

∑ (yi – μ)2 / N = 36.33

Example 2: For sample variance

Evaluate the sample variance of the given set of observations.

1, 3, 8, 12, 21


Step 1: First of all, calculate the sample mean of the given data set.

Sum of sample values = 1 + 3 + 8 + 12 + 21

Sum of sample values = 45

Total number of observation = n = 5

Sample mean of data set = ȳ = 45/5

Sample mean of data set = ȳ = 9

Step 2: Now value the deviation of the data values from the sample mean.

y1 – ȳ = 1 – 9 = -8

y2 – ȳ = 3 – 9 = -6

y3 – ȳ = 8 – 9 = -1

y4 – ȳ = 12 – 9 = 3

y5 – ȳ = 20 – 9 = 11

Step 3: Now make the above differences by taking the square of each term.

(y1 – ȳ)2 = (-9)2 = 81

(y2 – ȳ)2 = (-6)2 = 36

(y3 – ȳ)2 = (-1)2 = 1

(y4 – ȳ)2 = (3)2 = 9

(y5 – ȳ)2 = (11)2 = 121

Step 4: Now calculate the statistical sum of squares by adding all the above-squared deviations.

∑ (yi – ȳ)2 = 81 + 36 + 1 + 9 + 121

∑ (yi – ȳ)2 = 254

Step 5: Take the quotient of the ∑ (yi – ȳ)2 (sum of squares) and the total number of observations minus 1 to calculate the sample variance of the given data set.

∑ (yi – ȳ)2 / N – 1 = 254 / 5 – 1

∑ (yi – ȳ)2 / N – 1 = 254 / 4 = 127/2

∑ (yi – ȳ)2 / N – 1 = 63.5

Wrap up

In this lesson, we have learned all the basic intent of the variance with the help of solved examples. Now you can grab all the basics of the variance and able to calculate any problem of variance by following the above formulas and solved examples.


Best Language for iOS App Development

Have you begun development on your iOS app yet? If so, you should know about your growth choices. And if the thought of creating them has just occurred to you, the next inquiry would be to find the best iOS course on Udemy and learn which programming language is ideal for creating these applications. If you wish to predict why your device’s customers appreciate this technique so much and what are the possibilities for its development, you’ll need to do some deeper diving into the marketplace and comb through the customer evaluations. So, let’s check out how you can develop apps with the best languages and which ones are truly suitable for them.


Swift is the most popular contemporary computing language for iOS devices. It combines the greatest features of C coding and Objective-C dialects, and it is utilized extensively in a good deal of software development projects now underway. Descent, flexibility, isolation, and separation have all seen several updates, including the addition of current functions like containers, generic medicines, and others. The method of developing apps for iOS has gotten less rigid and more enjoyable in recent years. Storage can be handled dynamically in programs written in the Swift computer program, objects may be created before they are used, and matrices and numbers can be verified for overflowing. Engineers may also readily see any problems in the code, which cuts down on the amount of time required for testing and eliminates the possibility of producing code of poor standard.


Java is a global computer program that has several characteristics with languages that are comparable to C. As a consequence of this, iOS also makes use of an object-oriented broad-sense coding language for ios with tightly typed syntax. The conversion of Java original software to Objective-C for use on this platform is a straightforward process. Gain a deeper understanding of Java syntax. It is among the most widely utilized programming languages for ios development all over the globe, and it is used for a wide variety of purposes, including developing the system, business application development, and backend data analytics. Because of these characteristics, Java helps programmers to “Write Once, Run Anywhere” (WORA). This means that a Java system can be formed on any gadget, and it will be able to execute on any device that contains Java-simulated equipment.


Objective-C is a computer language that was developed as an enhancement of the C computing language to include support for object-oriented operating. In the early 1980s, Tom Love and Brad Cox of the technology business Stepstone, which had originally been known as PPI, were the ones who came up with the idea. It is a language that may be used for a variety of purposes, but its primary application is in the development of software for Apple’s operational platforms and the application programming interfaces (APIs) for those systems, Cocoa and Cocoa Touch. The attractiveness estimate on Stack Overflow places Objective-C at the 27th position, which places it three spots behind Swift. At this time, just 2.39 percent of engineers throughout the globe make utilize it.


Microsoft first presented it to the public in the year 2000 as an alternative to Java, which was its primary competition. It is a kind of coding language that is connected with the.Net infrastructure and uses an object-oriented approach. C# is now the seventh most popular programming language in the world, and it is utilized by 31.4% of all developers. This success may be attributed to the fact that the language’s design is both straightforward and complex. In addition to this, there are a few more considerations that will help you make a better-informed decision about this computer program.

  • Open Source: Because of its popularity among developers, it transitioned into free software in the year 2014.
  • Responding: When it relates to the speed of execution, C# offers comprehensive and quick reaction time throughout the compilation process.
  • Library: C# is quicker than other languages because it provides a wider variety of frameworks to choose from, each of which has its own set of preset routines.


HTML 5 is a front-end software program that is used to develop user interfaces for online applications by specifying the semantics and structure of its content. It is used with CSS and JavaScript in the process of developing interactive user interfaces for iOS mobile applications. Because HTML is among the simplest languages that can be learned by anybody, it is an excellent choice for those who are just starting out in the world of coding. If you want to design user interfaces for iOS applications that can be accessed both online and offline, HTML 5 is the best technology to employ. Because HTML 5, CSS, and JavaScript all operate together, you must also make sure that you have programmers on your staff who are very familiar with all three of ios programming languages. It provides:

  • Large quantity of available talent
  • Cross-platform compatibility
  • It is available for free use
  • Simple to pick up and put to use
  • Creates the ability to use applications offline.


You now have the knowledge necessary to create an iOS app from scratch. Developing your software in-house isn’t the quickest, cheapest, or simplest option anymore after everything you’ve learned. Writing your own code for an iOS app, particularly if you’re just starting out, is a long and arduous process. Hobbyists and those seriously considering a profession in application development may find it rewarding; professionals in the field will find it indispensable.

What Are The 4 Steps For Finding An Inverse?

Inverse operations are usually used in mathematical analysis to find the inverse of any given function. The inverse of an exponential function, for instance, may be found using a logarithmic function. In any case, our major goal is to emphasize the correct method for exactly determining the inverse of any futon. However, utilize the online inverse function calculator provided by if you need quick and accurate computations. You can quickly get the inverse of any mathematical function using this free inverse calculator.

We will be explaining how to get a function’s inverse in this technical article.

Let’s get started!

The Formula For a Function’s Inverse:

With the aid of the following formula, you can find the inverse of a function:

f1(x) = y where f(y) = x

But instead of using this formula, which takes a long time to calculate the output, utilize the free online inverse function calculator for prompt and accurate results.

Graph of the Inverse Function:

You need to be aware of the fact that the graphs of the functions y = f(x) and x = f(y) are identical. What has just happened is that the variables x and y have been changed in order to graph the equation y = f(x).

How Do I Calculate Any Function’s Inverse?

Well, this part seeks to be focused. We’ll be solving a few instances right now to further develop your point. Let’s discover how!

Example No. 1

Discover the inverse of the following function:

y = x + 3x


The variables x and y in the above function will first be reversed as shown below:

y = x + 3x

x = y + 3y

x = 4y

y = x / 4

This may also be quickly determined by utilizing the free online inverse function calculator. It is the necessary inverse of the provided function.

Example No. 2

Find the inverse of the following function:

y =x = y+11/13y+19


We will use the exact same procedures we used in example # 01 here in order to produce the results:

x = y+11/13y+19

y = x + 11/13x + 19

y(13x + 19) = x + 11

13xy + 19y = x + 11

13xy + 19y – x = 11

13xy – x = 11 – 19y

x(13y – 1) = 11 – 19y

x = 11 – 19y/13y – 1

This is the necessary inverse of the presented function.

Use a calculator for inverse functions:

Use a function calculator’s free inverse to improve the results of your calculations. Let’s look at how!

  • Your job title should be entered in the appropriate field.
  • Click the calculate button to see the results.
  • The result will appear right away on the calculator’s screen.

What a speed!

To Sum It Up:

Determining the inverse of the functions is not a child’s play as you need to focus and recall all the calculus concepts needed to carry out the exact computations. In this article, we covered how to determine a function’s inverse both manually and with the use of a free online inverse function calculator. You’ll benefit greatly from it, we hope.

Six Advantages of Freelance Writing

Everyone is curious about how to freelance, how much money they can make and what benefits they offer.

This article is for people who are interested in starting a freelance writing career. However, they might not be familiar with the steps and the benefits. It can also be useful for students who need help with studying thinking “who will do my thesis for me?”. This is what I felt when I began my freelance writing career. No one was there for me. It is easy to become a freelance writer today. All you need are good writing skills and a command of grammar.

Many people don’t enjoy the office job they aren’t happy to do for six to seven hours. Writing freelance offers many benefits, such as flexibility in work hours, independence from the workplace, and freedom of time. Office-based writers must also complete their targets before they leave the office. They must also follow all rules and regulations established by office management.

Nearly two months have passed and I still receive emails from people wanting to know how they can set up their paper writing business and what benefits they could enjoy. After reviewing these emails, I decided that it was time to share the many benefits of online writing with people.

  1. No office restriction

This is the best advantage of freelance writing. Once you begin working as a writer you will be familiar with its flexibility. There will be no official restrictions, no rules, and no office politics. Office politics is something that many employees dislike. It was the most frustrating and troubling part of office life for me. It was very satisfying to work as a freelancer, compared to my job at the office.

  1. There is no workplace boundary

A worker in an office may be well aware of the difficulties associated with sitting for seven hours. Freelancing removes all these shackles and allows writers to work wherever they want. Freelancing does not require writers to be locked in a room. Freelancers can choose to work in a place that is flexible and where they feel at ease.

  1. Time Independency

It is very different to work as a freelancer in an office setting. Office employees must arrive on time to work. Otherwise, their salary may be taken. Office employees dislike the timing of their work hours. They don’t like having to get up at 5 AM to run to catch the bus. It’s possible to be free of such rigid office schedules by freelancers. You can begin your work at any time of the day.

  1. Diverse Work Options

One thing I want to mention is the diversity of writing work. As freelance writers, students can hire you for assignments. Entrepreneurs can hire you as a marketer for their products and services. You’ll find your writing more interesting if you have a variety of work.

  1. Increase Work Creativity

It is very different to write in a stressful environment than to work in a friendly one. A person can be more creative and productive when they work in a relaxed and open environment.

  1. Income is dependent on written words

You will not receive a fixed salary like an office job. It will depend on how many articles you write to make extra money. This is where the fun part of freelancing is when you have your own income.

Best Essay Writing Tips for College Students

Like any article, short speech, or abstract, an essay has a certain composition and format. Therefore, the general requirements for writing and formatting, as well as for the design of the list of references and appendices should be followed. Choosing a topic should be the first and most important step in preparing to write an essay. According to the custom essay writers, the theme of the work should be relevant, i.e. meet the current issues of research in a particular field, demonstrate novelty, deep and at the same time differentiated approach, and be based on the individual scientific preferences of a student.

Execution of the essay after the selection and formulation of the topic is usually divided into the following stages:

  1. Drawing up an outline;
  2. The search for scientific sources on the topic, their analysis, a compilation of bibliography;
  3. Preparation of theoretical material (substantiation of the relevance of the chosen topic, setting goals and specific objectives of the study, the choice of research methods);
  4. Conducting research. Description of the research process;
  5. Analysis of the obtained results;
  6. Formulation of conclusions and evaluation of the obtained results;
  7. Preparation of the text, technical design, and presentation of work to the teacher;
  8. Finalization of the text taking into account the comments of the teacher.

Here are tips from the professional writer on how to complete each of the above stages:

  • Drawing up a plan should not be missed because it allows you to create a template for further writing of the paper and optimally allocate your time;
  • In the introduction, it is necessary to briefly describe the problem, the state of its theoretical and practical elaboration, relevance, argue the feasibility of certain studies;
  • Searching for literature on the topic is quite a responsible stage, as it determines the degree of awareness of the student in the field of study. The search should cover both literatures from previous years and publications of periodicals of the last 5-10 years. Preference should be given to primary sources. Searching the Internet allows you to get the most up-to-date information about the state of the problem, the latest trends in modern research and their results, but requires a balanced and careful approach to assessing the quality and degree of the scientific validity of available sources;
  • Based on the studied sources, theoretical material should be collected and presented in an essay. The student is obliged to perform all stages of elaboration of the topic independently, referring to all the thoughts, views, and ideas, indicating their real authors and sources. The use of plagiarism is not allowed;
  • If the topic of the essay involves research, then appropriate scientific methods should be selected and analyzed. All the results that will be obtained during the study should be presented in the text of a paper and persuade readers of the veracity of a particular statement. However, it is important to indicate your own position and give relevant examples;
  • The final part of the essay should be general conclusions. The conclusions should briefly describe the main scientific, and practical results obtained in the work and inform about the achievement of the general purpose of the study;
  • Try not to forget about the list of sources used. It demonstrates the source base of the study, reflects the competence and ability of the author to work with the choice of literature and analyze it, and indicates what information was borrowed from other publications. The formation of the list of sources should begin from the moment of determining the topic of the essay and be carried out in accordance with the established rules.

6 Benefits of Distance Learning

Distance learning allows you to register into an institution and complete a course without attending physical classes. You attend classes through your phone, laptop, and other gadgets. Learning will also involve a lot of e-materials like books, videos, audio presentations, and live streaming.

Distance learning is a breakaway from the traditional learning method. You do not see your teacher or have classmates in the same room. The approach to learning has shed off many elements that defined studying in the traditional sense. Is the method any beneficial to the student or will learners end up as losers?

Since students do not utilize physical campuses, institutions have reduced the fees charged. It makes education an affordable event for the most prestigious universities and institutions around the world. Consequently, it has made education more accessible to students at all levels.

Relocating to another city is also expensive. You have to sell your property or maintain two houses in different locations yet you are not utilizing them optimally. Distance learning allows you to study from the comfort of your home without relocating and bearing the heavy cost of living in another location.

2. Access to prestigious universities and courses

Physical campuses restricted access to a quality education because universities or colleges would only admit students based on their physical capacity. It made courses in these universities extremely competitive and out of reach for many students.

Distance learning has opened universities and colleges to more people. You can enroll in the most prestigious university or college while living in another continent. You can also take several courses in different institutions at the same time as long as you can balance the study hours effectively. Distance learning helps you to achieve your career goals easily.

3. Freedom to pursue other dreams

College years also offer opportunities to pursue other dreams. You may start a business, take up a job, or utilize your talent in sports and art. Physical learning confines you to a particular location where the pursuit of such dreams might curtail. Distance learning is the secret to pursuing other dreams while still studying.

Distance learning allows you to follow classes from the comfort of your room after work or upon the completion of a tournament. Such opportunities expand your potential and career prospects. It is a perfect step towards self-actualization.

4. Offers flexibility

Distance learning comes with flexible learning hours. With recorded classes, you can study in the evening after work or early morning before heading out. In case you miss a class, you can still catch it when done with responsibilities or engagements.

A flexible schedule helps you to attend to other issues. For instance, you can be with family during important events without worrying about missing classes. The flexibility increases your potential, especially helping you to do more with your time.

5. A critical lesson on self-motivation and management

Successful distance learning requires a lot of self-motivation and management. You must manage your time to avoid skipping classes because you are not on campus. You also have to create the right study space to complete your work. With no physical incentives to put you in line during studies, it is upon you to make distance learning work.

The time management and self-motivation skills learned will transform your life henceforth. They are crucial in your professional life. They boost your potential because you can do more without supervision.

6. Self-paced

Distance learning happens at your pace. The institution will indicate the hours you have to clock in before graduation. With the materials available, you can speed up your learning or slow down based on your engagements at each moment. It is a perfect way to avoid pressure when studying.

Distance learning has opened more opportunities for learners. It has made pursuing the desired courses cheaper and more efficient. It is also a ticket to freedom through a flexible schedule and self-paced learning. If you need to pursue other interests like business, sports, or art, you should embrace distance learning.
