1. The problem statement, all variables and given/known data I have two problems from my differential equations assignment that I'm having difficulty with. I would appreciate some guidance! 2. Relevant equations http://img10.imageshack.us/img10/3397/questionsk.th.jpg [Broken] 3. The attempt at a solution for no.10 I used reduction of order with the assumption that one solution is y1=e^x I got y2=xe^x my question is for this question do I solve the unhomogenous equation by variation of parameters to solve for the particular solution And from there use it for the General Solution ? ( yg= yh+yp. For no.7 I multiplied by x^p y^q and found the partial derivatives My and Nx. Inorder for it to be exact, I equated the partial derivatives and found my values for p and q. They came out to being fractions and my final solution is extremly messy with fractions. Is this is correct approach? Thanks.
