# Basic concepts in differential equations.

Differential equation is an equation which is a derivative of the dependent variable with respect to the independent variable. It is used to determine the order and degree of polynomial equations. The derivative with the highest order tells the order of the differential equation. The degree of the polynomial in the differential equation is the degree of the highest order derivatives of the differential equation.

These are a few types of differential equations:

Ordinary differential equation: It is a differential equation that depends on only one independent variable.
Partial differential equation: It is a differential equation which depends on two or more independent variables.
Linear differential equation: It is a differential equation in which derivatives appear in the first degree.
Non-linear differential equation: It is a differential equation in which the derivative is more than the first degree.
