1. The problem statement, all variables and given/known data y''+(1/y)*(y')2=0 2. Relevant equations 3. The attempt at a solution This is another problem I am having trouble with. I have done searches around the internet, but seen that all "non linear" ODE of second order involves a non linear form in a non differential term (like y''+xy^2=0, or something like that), instead of the DE term. Punching through wolfram alpha gave a really simple straightforward answer, so I believe it shouldn't be too hard, as long as I get the general method to solve it. thanks in advance.
