If you are testing for exactness in a d.e. that is in the form of Mdx + Ndy = 0(adsbygoogle = window.adsbygoogle || []).push({});

Do you compare M and N for the exactness test?

Or do you compare their partials?

Also when you are actually solving it, do you anti differentiate in respect to a partial the M term (or n). Or do you need to different the functions in front of the operators first?
