I am trying to integrate the the normal vector to the surface of a hemisphere but am having some trouble. I am pretty sure that the x and y components will cancel out, and that the z component in spherical coordinates is R*Cos[theta] but for some reason I am having trouble really understanding how to do it.(adsbygoogle = window.adsbygoogle || []).push({});

I know this is really basic but I'm horrible at vector calculus. Any help is greatly appreciated. Thanks
