Ordinary DE

• Ordinary Differential Equation is one which relates a function y = f (x) to one independent variable x and its derivative/s. Assuming that y is a function of x, the following are examples of ODE

Partial DE

• A partial differential equation is one which relates a function of two or more variables to its partial derivatives.

Order and Degree

• Order of DE – the highest order of derivative contained in the equation.

• Degree of DE – the degree of the highest order of derivative contained in the equation.
