Just wondering if anyone could help me out with some problems I'm having with differential calculus.(adsbygoogle = window.adsbygoogle || []).push({});

Firstly, can anyone confirm if I sketched the region in image 1.jpg correctly (shown in 2.jpg)? I've done questions before where it just says |z|<2 and I know that it looks like a circle, but in this case the Re z at the end of the 2 just got me really confused.

Also, in image 3.jpg I have no idea as to how to even approach section a and I'm pretty sure I can't do b and c without understanding a. Can anyone help me out with this? Any hints or something because I've been staring at it for a while now and not getting anywhere (obviously).
