Biholomorphic map
I found a question which reads
(1) Construct a biholomorphic ma f : \Omega1 \to \Omega2, where \Omega1 is a unit disc and \Omega2={z \in C 0<Arg(z) < \frac{\pi }{4}}. Show the map as a composition of simpler biholomorphism and write the combined formula for f(z).
Please can anyone help me where to start and how to start. i am having trouble to get started.

This question would be better suited in the Analysis subforum.
For the question, can you transform the disk into the upper half plane, and then this into ?

sorry, i couldnt get what you are saying . please can u explain it a bit.
