I'm working on a problem in the chapter "Surface Integrals of Vector Fields".
Problem is to evaluate a vector function over the top half of a sphere.
In the solution, the Professor states: "In this case since the surface is a sphere we will need to use the parametric representation of the surface."
In the previous problem the surface was a paraboloid and the surface of the paraboloid did not need to be parameterized.
My question is: "Why does the fact that the surface is a sphere instead of a paraboloid require the surface to be parameterized?"
Thank you
