Thread: Challenging problem

I've been trying to solve and find the solution of this problem by
method of exact equations but eventually I got stuck.

Thank you in advance.

[y^(x) Cos(2x) -2e^(xy) Sin(2x) + 2x]dx + [xe^(xy) Cos(2x) -3]dy = 0

May I ask, is the a chance that the term above in red is

?

I checked my notes again to confirm. But, it is:

You'll notice that you've changed the term from your first post. When you say notes, are you refering to classroom notes that you took?

Sorry my mistake.

is y^(x) Cos 2x

Yes the notebook I used to work on.
