Hence, an indepth study of differential
equations has assumed prime importance in all modern scientific investigations In this chapter, we will study some basic concepts related to differential equation,
general and particular solutions of a differential equation, formation of differential
equations, some methods to solve a first order - first degree differential equation and
some applications of differential equations in different areas 9 2  Basic Concepts
We are already familiar with the equations of the type:
x2 – 3x + 3 = 0
