Hi All,
Sorry if this is on the wrong thread, I am not sure where complex numbers go and I am not an American student!
I am stuck on part ii of this question. I got -1 - i as my answer for part i. I am confused whether the Arg (z) should be -3pi/2 or pi/2. I understand that if you squared the z value you get 2i, which then gives the Arg value as pi/2. But if I took the 2 out and made it 2Arg(z) then I would get -3pi/2. I understand that capital 'A' in arg indicates the principle argument, but both these values lie between the boundaries for this?
Thanks
