comment Functions that are their own inversion.
@user121330 Phrases like "it's easy" and "it's trivial" are common mathematical parlance. Like a lot of mathematical language, they have a slightly different meaning to their common English meaning. In particular, when someone describes something as "easy" or "trivial" they often mean that it can be done without introducing significant new ideas, or without requiring a sudden flash of insight. In particular, a calculation or derivation taking many pages of routine algebraic manipulation can be described as "trivial" even though most non-math people would say it is hard.

comment Statistics: Where did this function for normal distribution come from?
They are axioms for the purposes of this answer (i.e. they're assumptions that I am making without any justification). There isn't a name for them that I'm aware of.

comment How to find remainder modulo $n$, when $n$ is a large number
Dear editor - not only did you screw up the math in this post by editing it, you also screwed up the formatting. I have reverted your edit.
