if you did the int by parts correctly, you should only arrive at one solution ... how did you go about this?

e^x x e^x: x e^x 1 e^x : e^x 0 e^x : 0 I get: x e^(x)  e^(x) if i did it right

1 e^(1)  e^(1) + 0 e^(0) + e^(0) \[\frac{1}{e}\frac{1}{e}+0+1\] \[\frac{2}{e}+1\]

\[u=x\] \[du=dx\] \[v=e^{x}\] \[dv=e^{x}\] \[\int\limits_{0}^{1} xe^{x}dx=xe^{x}_{0}^{1} + \int_{0}^{1}e^{x}dx\] \[\int\limits_{0}^{1} xe^{x}dx=1e^{1} + e^{x}_{0}^{1}\] \[\int\limits_{0}^{1} xe^{x}dx=e^{1} + e^{1}+1\] \[\int\limits_{0}^{1} xe^{x}dx=2e^{1}+1\]

@Hunus your integrand is positive (on (0,1)) ...your answer is negative...this tells you you are not correct.

Yea, I see where I went wrong on the \[e^{x}_{0}^{1}\] I put e^1  1 instead of e^1 (1)
