Hi, can anyone help me solve this:

First make a substitution then use integration by parts to evaluate the integral:

$\displaystyle \int^\pi_0 e^{\cos{t}}\sin{2t} dt$

So far I have:

$\displaystyle \int^\pi_0 e^{\cos{t}}2\sin{t}\cos{t} dt$

let u = $\displaystyle \cos{t}$

How do I do the next part?
