How do you determine a solution to a DE if you know the DE is exact? My professor (or possibly my notes) did a horrible job of explaining how to do it and the book does an even worse job explaining how to do it. For example, how would i go about solving this equation? I need to find c, the constant.(adsbygoogle = window.adsbygoogle || []).push({});

[tex] ( - 2xy^2 + 2y)dx + ( - 2x^2 y + 2x)dy = 0[/tex]

I know that I differentiate each part by dx/dy and dy/dx to attain:

[tex]- 2xy + 2\frac{{dx}}{{dy}} = - 2xy + 2\frac{{dy}}{{dx}}[/tex]

But where do I go from that point?
