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?
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.
there is a technique here.. its called IDEIS... integrate, diffrentiate, equate, integreate, solve! integrate m in respect to x, diffrentiate the result in respect to y, equate it with n, integrate it in respect to y and last solve the remaining to get the general formula.
@IiIbao You can use the integrating factor method to make them exact provided that it is in the same form but My is not equal to Nx (There is another video on this).

Fantastic, The first video was a bit confusing, but this was so much better, maybe switch the order on this one vs. the other one b/c this seems a bit easier than the first.

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

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

He talk about it in the Intuition 2 vid.

Hey awesome video.
On a side note, you can solve this in an easier method.... It is a separable equation!
