∫(u)->(1) (y1*e^(-y1)) - (u*e^(-y1)) dy1 I forgot a lot of my calculus and appreciate anyone who can integrate this!

I dont understand your notation, but, i can help you with this integral $\displaystyle \int x e^{-x}dx=\int x (-e^{-x})'=-xe^{-x}+\int e^{-x}dx=-xe^{-x}-e^{-x}+C$
Thanks to felper, people can see what the OP posted. People shouldn't delete their own problems, it could be hepful for other ones.
