Can someone either explain here, or link me to an online document, on how to do surface integrals over surfaces in 3d (not simple ones like planes with x, y, or z held constant). I learned this back in Calculus 2 five years ago, and now I need to do it for my Electrodynamics course and I can't really remember how to do it?(adsbygoogle = window.adsbygoogle || []).push({});

For example, what if I have a function that I want to integrate over a triangle with vertices (1, 0, 0), (0, 2, 0), (0, 0, 3)?

I think it had something to do with with finding a unit vector normal to the surface (which I can do), but no idea where to go from there.
