Suppose you are given an equation of the form:
Suppose you are given an equation of the form:
:(1) <math>M(t,y) + N(t,y)y' = 0\,</math> or <math>M(t,y) dt + N(t,y) dy = 0\,</math>
:(1)<math>M(t,y) + N(t,y)y' = 0\,</math> or <math>M(t,y) dt + N(t,y) dy = 0\,</math>
Before we begin solving it, we must first check that the equation is exact. This means that:
