Jan 22	comment	How to read letters such as $\mathbb A$, $\mathbb B$, etc., or $\mathfrak A$, $\mathfrak B$, etc.? That's an A? I always thought it was a U...
Jan 4	comment	What's a proof that the angles of a triangle add up to 180°? @ Joe Zeng: Yes but when you "fold" the triangle you are just reflecting the top vertex of the triangle onto another line parallel to the base of the triangle (but that line just happens to be the base itself, i.e. a line is parallel to itself). The reflection preserves angles and the final geometric analysis is similar (just rotated 90 degrees). I'm not disagreeing with you per se, just pointing out how your "folding" technique is actually more rigorous than you give it credit for!

Aug 25	comment	Algebraic vs. Analytic curves Thanks for the reference!
Aug 16	comment	Algebraic vs. Analytic curves Sorry, what do you mean by "depends on the level"? If you are implying that my example is too simple to merit a more robust algebraic approach, that is not quite what I'm after. I'd like to know if such an approach exists regardless. I'm specifically looking for the existence of techniques beyond "the calculus".
Aug 16	comment	Algebraic vs. Analytic curves @PatrickDaSilva, I was thinking along the same lines, that there'd be some sort of analytic framework to take the limit of some polynomial-like object, just not sure if this has been done or what it might be called.
Aug 16	comment	Algebraic vs. Analytic curves I guess I'm trying to avoid referring to "algebraic geometry" because then the answer is just "your curve is not a polynomial". I guess I could rephrase the question as "What makes polynomials special?", or "Are there ways to represent transcendental curves as polnomial-like structures that makes them ammenable to the tools os algebraic geometry?" but I'm starting to use words outside of my comfort zone at that point.

Jun 26	comment	Proof that $\mathbb N $ is finite I would actually take issue with the statement that there are only finite many words in the English language, and then migrate this question over to english.stackexchange.com
