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 (1)
sin x + cos x = 0
