Overview to Course

In this video we discuss the concept of ODE, some of the basic definition Order of ODE ,Degree of ODE, Homogeneous ODE and Some of Examples.

Introduction

The solution of differential equation is a family of curve that satisfy the differential equation. Order of derivative is equals to no of constant appear on the solution.

Solution Of Differential Equation

For first order differential equation you can plot the slope field. We know that first order derivative is a slope of tangent to the curve and thus if we plot small line with that slope we can plot a field in space.
