I can't seem to solve this seemingly simple integral. It's probably easy but I don't see it. Anyone care to try? Thanks.

Integral of (e^x)*(e^(e^x)) dx

Integral of (e^x)*(e^(e^x)) dx - Feb 14th 2009, 01:04 PMskeeter
let $\displaystyle u = e^x$

$\displaystyle du = e^x \, dx$

$\displaystyle \int e^x \cdot e^{e^x} \, dx$

substitute ...

$\displaystyle \int e^u \, du$

now finish. - Feb 14th 2009, 01:25 PMpianopiano
Oh, thanks.

I feel stupid now. Lol.
