Given the intergral
where is the sphere
I need to:
a)Evaluate the surface integral directly
b)Use Gauss's theorem to evaluate the integral
I have looked through my notes and searched the web. I have found a few examples but they aren't the same as this question and i cant work out the differences.
Any pointers in the right direction would be helpful, because i understand the theory of surface integrals, but am struggling to mathematically apply it.
