# Differential Equation...Sturm Liouville stuff watch

1. http://i258.photobucket.com/albums/h...g?t=1264004749

Basically i just solved it, but have constants A and B that will only satisfy the boundary condition y(0) = y(pi) = 0 if A = B... But according to how the question is worded, I'm meant to be able to do the first part without knowing the boundary conditions, but solely on the fact that n is positive integer?
2. y(0) = y(pi) = 0 *are* boundary conditions.

If you don't assume n to be an integer, you should find that you need A=B=0. It's only for particular values of n that you can get a non-zero solution.
