A differential expression M(x,y) dx + N(x,y) dy is an exact differential in a region R of the xy-plane if it corresponds to the differential of some function f(x,y) defined on R. A first-order differential equation of the form M x ,y dx N x ,y dy=0 is said to be an exact equation if the expression on the left-hand side is an exact differential ...

previous example, a potential function for the differential equation 2xsinydx+x2 cosydy= 0 is φ(x,y)= x2 siny. We now show that if a differential equation is exact and we can find a potential function φ, its solution can be written down immediately. Theorem 1.9.3 The general solution to an exact equation M(x,y)dx+N(x,y)dy= 0 is defined ...

Exact Equation If given a differential equation of the form , + , =0 Where M(x,y) and N(x,y) are functions of x and y, it is possible to solve the equation by separation of variables. However, another method can be used is by examining exactness. The whole idea is that if we know M and N are differentials of f,
