Isn't Problem 1 a real analysis problem?
Problem 2
By brute-force, maybe.. Is there any other way than computing the difference quotient?
Problem 3
Identity theorem
Problem 4-6
They all follows Schwarz's Lemma. The only trick is to construct a composite map that map back and forth and eventually unit disc into itself.
Problem 7
I still cannot help quoting the Baire category theorem since Prof. Bell said it's OK.
