>>13731157How the fuck did you get the impression that I didn't know this? I wasn't saying that you were asking me for the length of a word. I was saying that you were asking me for the "length" of something which is not comparable in any coherent way to the "length" of a side of a polygon, as if you were talking about a word. It was a stupid fucking question. D isn't a "line segment" in the usual sense of the word, I've already said that it is better understood as a "point with tangency data," and it's formally described via an R-algebra isomorphism to the ring of dual numbers.
Me providing a convincing answer to the question, which is ill posed at best, couldn't POSSIBLY bring us any closer to figuring out what the fuck your "trapezoid with infinitesimal side length" actually fucking is.
