Homework Statement
Find all the complex numbers defined with:
[tex]\left | z^2 - 1 \right | = \left | z \right |^2[/tex]
[tex]arg(z+2i) = \pi / 4[/tex]
Homework Equations
z=x + yi
agr(z)=ArcTg(y/x)
The Attempt at a Solution
I've changed z with x+yi but it turned out to be a forth order equation to get solutions for y. So I'm guessing that isn't the right way.
Any hints?
