(c) what have you tried?

No, no one here will solve this for you. Why did you think otherwise? Free math help means that we offer help for free. That is far from us doing your homework for you. If you want help that is great but you will play by the forums posting guidelines.
Show us what you have done and where you are stuck and you'll receive help.

This is help only on Q#1. These are to be Marked, Learned, and Inwardly Digested!
If \(z=a+b\mathcal{~i}\) then \(\Re(z)=a~\&~\Im(z)=b~\) moreover \(~|z|=\sqrt{a^2+b^2}\)
Then the conjugate is \(\overline{z}=a-b\mathcal{i}\)
Perhaps most importantly \(\large\dfrac{1}{z}=\dfrac{\overline{z}}{|z|^2}\)

This is one of the strangest replies I have seen. You really signed up just to write that post. And I thought I was strange.
