Wow thank you, can't believe I forgot to apply the product rule...
actually I got this the first time I tried the problem, but the problem with doing it this way is when I get all the y' on one side there doesn't seem a way to take out the y'.
((2/y')-(y'/y))=(((-e^-x)(cos(y/2)))-(e^-x)(sin(y/2)-(1/x))
((2y-(y'^2))/(y'(y)))=...
