Exact differential equation.
Answer:-
An exact differential equation is formed by directly differentiating it's solution without any other process.
★ Mdx+Ndy=0, is said to be an exact differential equation if it satisfies the following condition I.e (dM/dy)=(dN/dx)
Where dM/dy denotes the differential co-efficient of M with respect to y keeping x constant and dN/dx, the differential co-efficient of N with respect to x, keeping y constant.
