Question

I. explain the condition of exactness of the linear differential equation.

Answer 1

Answer:

The linear differential equation is where the order of differential equation is 1.

And we say the differential equation say in the form:

$M(x,y)dx+N(x,y)dy=0$

Then the differential equation  is said to be exact when:

$M_y=N_x$

Where$M_y \text{is partial derivative of M with respect to y}$

And $N_x \text{is partial derivative of N with respect to x}$
