# Ordinary differential Equations

In the post, we define Ordinary differential Equations and also provide related examples so that the learners van understand the concept easily.

### Ordinary differential Equations

A differential equation in which ordinary derivatives of the dependent variables with respect to only one independent variable occur is called ordinary differential equations.

Examples:

1. $\frac{dy}{dx}+ycosx=sinx$
2.                $\frac{dy}{dx}=7x+5$
3. $\frac{dy}{dx}=cosx$
4. $\frac{d^2y}{dx^2}+xy&space;\left&space;(&space;\frac{dy}{dx}&space;\right&space;)^2=0$
5. $\left&space;[1+&space;\left&space;(\frac{dy}{dx}&space;\right&space;)^2&space;\right&space;]^{3/2}=\frac{d^2y}{dx^2}$
6. $\frac{dy}{dx}&space;+\left&space;[1+&space;\left&space;(\frac{dy}{dx}&space;\right&space;)^2&space;\right&space;]^{3/2}=0$
