    \[y \prime \prime + ( \sin x ) y \prime + ( \cos x )y = 0 ; y(0)=0 , y \prime(0)= 1\]

    i'm not too sure when it's regarding trig stuff, we haven't really gotten into that. what we've done is always do \[y = \Sigma (AnX^n)\], then take the first and second derivatives of it. after, plug it all back int the original equation.

    i'm not sure how to find it without going through the power series. and even at that, i think it'd be messy :(
