Applications of Differential Equations

This paper explains the introduction on Differential Equation and it explainsbasic concepts on these. It gives a few examples to illustrate how practical problems are modeled mathematically and how Differential Equations arise in them. It is important for engineers to be able to model physical problems using mathematical equations and then solve these equations. This article attempts the concepts of LCR circuits in electrical circuits, free vibration of mass using Differential Equations.
