Why is Lil' Wayne in the related videos?

YOU CAN ALSO JUST INTEGRATE M AND N, THAN PLUS EACHOTHER, PLUS A CONSTANT (like this ? :)), it's much more easy ! :)

@kourosh89 watch his "exact equations intuition 2" video and it'll all be clear

I don't understand why finding psi is "solving" the differential equation.

@TheFredfunk M is already a partial derivative of Ψ respect to X and N is already a partial derivative of N respect Y, then if it's an exact equation the partial derivative of M and N are equal. When you takes those partial derivatives you'll know if it's exact or no and if you can solve it using this method. He talk about it in the Intuition 2 vid.

question. why did you do partial differentiation of the M function with respect to y when in the formula you showed it was partial with respect to x plus partial with respect to y dy/dx?

You are an absolute lifesaver. I cannot thank you enough!
