(adsbygoogle = window.adsbygoogle || []).push({}); Trying to solve the following boundary value problems.

y'' + 4y = cos x; y(0) = 0, y(pi) = 0

y'' + 4y = sin x; y(0) = 0, y(pi) = 0

The answer key says that there's no solution to the first part, but there is a solution to the 2nd part. I'm really lost and am not sure how to go about this. I'd greatly appreciate everyone's help on this!!!
