## Homework Statement

graph |z-1|=1 and then graph z^2

## Homework Equations

z=x+iy

## The Attempt at a Solution

well, |z-1|=1 => |(x-1)+iy|=1,

squaring both sides. we get, (x-1)^2+y^2=1. This is a circle. But how am i supposed to get z^2 from this? I don't know what to do with the inequality since i can't algebrically isolate the z.
