Thread: Exact equation

I already know this equation is not exact. The thing is, I never learned how to do partial derivatives so that is what I need help with. The equation is
I know that the sign in the middle needs to be + so then you have .
Then M= and N= . So, I need help getting .

To do partial derivatives, just hold all other variables that u r not taking the derivative constant

So
