What is differential equation?
An equation that involves a relationship between a function and one or more derivatives is called a differential equation.
Example: a * dy/dx + x = y A Derivative form
dy/dx = cos x
Above are the examples of differential equation since it involve a derivative form and the function in form of x and y.
ax2+bx+c=0 or x * sinx - x=1. These equations have variable x but do not include their derivatives hence these functions are not differential equation
Hyperbola Equation is not a differential equation
Similarly y=sinx not a differential Equation
For nth order
