comment The Shortest Distance Between 2 Points On The Earth
@xavierm02 It's not obvious to me that fixing one of the points does not change the uniform distribution of the other point, or perhaps I'm just not seeing it. Can you explain?

comment Logic behind dividing negative numbers
I most definitely disagree with the first two sentences. Mathematics is not a game of symbols. It should have a concrete foundation and it is good that the original questioner is trying to give meaning to the abstract notion of division.

comment Area of projected surface
I'm looking at the part you just added and I am not seeing the parallelogram. Instead I see a curve $z=x^2$ on the bottom of the "parallelogram" for example, and $z=x^2+4$ for the top.
