Evaluating integral with $e^{\sin x}$ I had this integral $ \int e^{\sin(x)} {\sin(2x)} dx$ 
I tried to split it up using integration by parts but I can't evaluate integral of $e^{\sin x}$

By parts works perfectly,
$$\int2\sin(x)\left(\cos(x)e^{\sin(x)}\right)dx=2\sin(x)e^{\sin(x)}-2\int\cos(x)e^{\sin(x)}dx\\
=2\sin(x)e^{\sin(x)}-2e^{\sin(x)}$$
