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 ...
