C++ program to find sin cos tan

Let me share with you C++ program that will calculates the sine (sin), cosine (cos), and tangent (tan) of an angle in radians.

#include <iostream>
#include <cmath>

int main() {
    double angle = 1.0; // Angle in radians (modify as needed)

    // Calculate sin, cos, and tan
    double sine = sin(angle);
    double cosine = cos(angle);
    double tangent = tan(angle);

    // Display the results
    std::cout << "Sine(" << angle << " radians) = " << sine << std::endl;
    std::cout << "Cosine(" << angle << " radians) = " << cosine << std::endl;
    std::cout << "Tangent(" << angle << " radians) = " << tangent << std::endl;

    return 0;
}

#include <iostream>

#include <cmath>

int main() {

double angle = 1.0; // Angle in radians (modify as needed)

// Calculate sin, cos, and tan

double sine = sin(angle);

double cosine = cos(angle);

double tangent = tan(angle);

// Display the results

std::cout << "Sine(" << angle << " radians) = " << sine << std::endl;

std::cout << "Cosine(" << angle << " radians) = " << cosine << std::endl;

std::cout << "Tangent(" << angle << " radians) = " << tangent << std::endl;

return 0;

}

Explanation:

First of all, we need to set the angle variable to the angle in radians for which we want to calculate the followings;
1. Sine
2. cosine,
Use the sin(), cos(), and tan() functions from the <cmath> library to compute these values and prints them to the console.
The angle value to compute these trigonometric functions for different angles.

You can modify the angle as needed.
