How to solve exact differential equation with an example: ( cos y+ y cos x) dx+ (sin x-x sin y)dy=0

In this video, we will learn how to solve an exact differential equation. A first order first degree ode can be expressed as M(x,y) dx + N(x,y) dy = 0. Then we state the necessary and sufficient condition for the differential equation to be exact. In the last part of the video, we will learn how to solve an exact ODE by solving an example:
( cos y+ y cos x) dx+ (sin x-x sin y)dy=0.
