Elementary Differential Equations with Applications - Course Outlines

Objective:

The word differential and equations certainly suggest solving some kind of equation that contains derivatives. Why should an erstwhile scientist or engineer study this subject? The answer is simple: Differential equations are the mathematical backbone of many areas of science and engineering in which we examine, albeit briefly, how differential equations arise from attempts to formulate or describe, certain physical system in term of mathematics.
