# Math Help - Integral of (xe^x)/(1+x)

1. ## Integral of (xe^x)/(1+x)

Yeah so do I use substitution or integration by parts???

2. if you set u=x+1, you will be able to break the function 2 integrals, and the e^(u-1) can be simplified to (e^u)/e which is merely a constant.
the first integral comes to e^(x), but the second one... i think you need the Ei function for it, correct me if i'm wrong
