I have a question. Fom what you have
. Isn't this ODE spearable?
The problem is
I’m trying to find an integrating factor to make this exact. To get the integrating factor “u”:
du/dy=u[(Nx-My)/M ]= u(1+2y2-1)/y=2y*u
If I multiply it by My and Nx, they don't equal.
Then my equation still isn’t exact. What did I do wrong? I feel like I’ve been over this 20 times already.
