intergrate: e^(sin theta) cos theta

How can I intergrate: e^(sin theta) cos theta

Thanks forany help.

$\displaystyle \int e^{\sin \theta} \: \cos \theta d\theta$

$\displaystyle u = \sin \theta$
$\displaystyle du = \cos \theta d\theta$

Making the subs:
$\displaystyle \int e^{\overbrace{\sin \theta}^{u}} \overbrace{\cos \theta d\theta}^{du}$

Are you saying that, when integrated, its the same as before?

that's not what o_0 said ...

$\displaystyle \int e^{\sin{\theta}} \cos{\theta} \, d \theta = e^{\sin{\theta}} + C$
