What I am unsure of is how to find the derivative of u. Since the original integral is integrating with respect to y, should I be finding the derivative of u with respect to y, and treat the x's as contants?

I think it's possible to solve it in terms of x
let u=x and dv=e^(-x(1+y))
and v= [e^(-x(1+y))]/(-(1+y))
I think it should work
if you want let
you treat y as a constant and x as a variable
(I am assuming you want to integrate in terms of x)
Alrighty then - I'll get to work. Thanks for the direction.
