The question reads:(adsbygoogle = window.adsbygoogle || []).push({});

"what part of the z-plane corresponds to the interior of the unit circle in the w-plane if

a) w = (z-1)/(z+1) b) w = (z-i)/(z+i)"

I really am having problems understanding what the question is asking. I dont understand what the w plane is, and in which plane is the unit circle, the z plane, or the w plane?
