This is the same as or .
That is a circle of points in the complex plane with center with radius 1.
So im stuck at;
Find the complex numbers with abs 1 for which it works that:
How do I solve it? I've tried almost everything I can use and do, the problem is I don't know where to start.
I've tried setting
|1-zi|=1 as z(roof)
Yeah I tried it, and it does not work. Well atleast it's not the same as the answer im supposed to get which is;
(+-)sqr(3)/2 - i/2
I understand exactly how you think, thought for me it's the Z part of |1-zi|=1 which ruins every and all attempts for me to crack this problem.
