I don't want to sound like a bigot

I'm really annoyed at how completely I've forgotten calculus.

You use it to derive the area of a circle! Or the volume of a sphere!

I had spent a decent portion of high school and junior high wondering where the fuck those two formulas had come from, and was beside myself with joy when I finally got to multivariate calculus and thus had the tools to derive the formulas for myself. :-D

I was extremely gleeful to go from first principles to the eqn we used to calculate the duration of orbits using the POWER OF MATH and also a pencil.
