comment Is it faster to count to the infinite going one by one or two by two?
@PaĆ­loEbermann Agreed, of course its all about the numbering of the sequence. We didn't properly define "slow". If we say "slow" means that it takes a longer time to spell the first $N$ members of the sequence then counting by two is slower, at least in binary it is. This is not a statement about the usual "slow" in mathematics: convergence speed.

comment Find $\mathbb E[(X+1)^2]$
It's $3\int_0^{\sqrt{3}-1}\frac{1}{1+x}dx = 3(\ln{(1+x)}\vert_{0}^{\sqrt{3}-1}) = 3\ln{\sqrt{3}}$

comment Show basin of attraction has only one connected component
You didn't use the polynomial of degree 2 yet... If you look at $f^\prime(z)$, how many critical points are there? Can a critical point lie both in $U$ and $V$?

comment Prove that if a set $E$ is closed iff it's complement $E^{c}$ is open
@Dominic Michaelis Of course. Like you and Mariano Suarez-Alvarez said the definition is important. So user77107 simply proved a different characterization of closed.

I also thought that this is the definition of closed...
