Homework Statement
Problem #7 in this old exam: http://math.njit.edu/pdfs/222ex1.pdf
... note: i didnt care about getting the IVP solvied... this is just practice and getting the general solution was all i cared about doing
2. The attempt at a solution

I think i confirmed my answer in a cas. But my confussion is if i plug the original differential equation, without making that substitution, that i get a different general solution... and I'm not entirely sure if that's to be expected.
In short, is my answer correct :P
3. Quick question about a different problem
Problem #3-A on that old exam:
"(d/dx)[sec(x)y]=x ...get general solution"
should the left side be expanded first, and then work the problem, or am i not seeing some easy way to separate this thing right away.
