find the range for
$g(z) = z^2$ for $z$ in the first quadrant, ie $Re z > 0 $ and $Im z > 0$
Why is the answer $Im w > 0$.
Similarly, how do i go about finding the range for:
$p(z) = -2z^3$ for $z$ in the quarter disk $|z|<1$, $0<Arg z<\frac{\pi}{2}$
I am confused as to how to determine the answer, what is the methodical approach to tackle this problem?
thanks.
