# Math Help - Integral Problem

1. ## Integral Problem

Hi all, looking for the long answer to:

$\int ye^{-y(1+x)} dy$

from 0 to 1

thanks!

if im asked $\int ye^{-y(1+x)} dx$ would there be a difference?

2. integrate by parts treating x as a constant--your answer will still have x in it

if im asked would there be a difference?
yes -- here you treat y as a constant and it would be easier

the Ad would be simply -e^[-y(1+x)]
