Hello. I was reviewing for a big test i have tomorrow, and while doing problems out of my book i came across this one...
I just can't seem to figure out how to separate the variables.

You can't because it s not separable
Set it up as a liner DE
y' +cos(x)y = xe^(-sin(x)
Your integrating factor is e^(sin(x)
d(e^[sin(x)y]/dx = x
y = x^2/2*e^(-sin(x) +c e^(-sin(x)
