@futurebird Of the few I understood, 43 comes closest to an ambiguity that annoys me. What does sin²x mean?
I've seen it used for both. If it's the first answer to 43 then it must also be my first answer below, mustn't it?
My sister (independently) asked one of her mathematical physics lecturers about it and he said it was obvious from the context. Super!
Also, what does x/y/z mean? (x/y)/z or x/(y/z)? One of my computer science lecturers said it was formally undefined (by a vote at some mathematical congress or something) but I've not been able to find a reference.
You can do all the things to it that you're allowed to do with continuous functions as long as you are only looking at an interval that doesn't cross zero?
It's difficult I seem to remember to talk about continuity without starting "continuous in x if for ever epsilon there is a small intervall around x , etc etc".
The function is "smooth" everywhere where it's defined. One has to admit this.

oh, and the fifth octant is buried a hop, a skip, and a jump away from the fifth elephant, and it is a terrible cross between an octopus and an ant, and probably the source of the dungeon dimensions.
@futurebird
most of these, I can accept either way, so long as a given book or document spells out which convention they're following, and sticks to it consistently. But people who think f(x)=3 is "increasing" are not just wrong, they're spreading misinformation, and probably cackling with gleeful evil as they do so.
