Efficient Methods for Finding the Integral of e^(2x)sin(e^x)

[rickp]

I tried several ways to find this it's just making me confused.
Integral of e^(2x)sin(e^x)dx

I tried Integration by parts but i can't seem to find out the integral of sin(e^x).

how about letting u = e^x... and you do know that e^(2x) = e^x * e^x so...

hm, thanks ill try that

Here's another hint, you will eventually need to use integration by parts.
