For the part highlighted in green, why doesn't negative infinitiy cancel with the negative near the x, and give us infinity? Instead it gives us 0. I know a number to thr negative infinity power is 0, just thought 2 negatives made a positive so was wondering why not here. And also, would thus converge or diverge?
(a) Find a conjugacy C between G(x) = 4x(1-x) and g(x)=2-x^2 . (b) Show that g(x) has chaotic orbits.

I have the following example in my analysis textbook "Let A = [0,1[. We prove that A does not have a maximum. Suppose A has a maximum M. Then M ∈ A, so 0 ≤ M < 1. Therefore, there exists an x ∈ R such that M < x < 1. For this, we have 0 ≤ M < x < 1, which means x ∈ [0,1[ = A and x > M, contradiction." I dont really follow it from 'Therefore', how do we know that there exists an 'x' such that 'M < x < 1'? If able please explain it in a bit more detail, thank you in advance.
I'm working through a 2D PDE and i've gotten stuck (if the rest of my work is correct). so I'm getting confused checking the boundry conditions. first, no where says that a has to be a finite number so I dont know if this checks out (this might be a question for my teacher so no worries if you cant answer that). second is u(x,y=0,t) I'm not getting zero, I'm not sure where I'm going wrong?
Prove that if A−1exists, then there can be no nonzero y for which Ay = 0.
