Mapping a complex circle to its square

Click For Summary
SUMMARY

The discussion focuses on graphing the complex circle defined by the equation |z-1|=1 and subsequently determining the graph of z^2. The equation |z-1|=1 translates to (x-1)^2+y^2=1, representing a circle centered at (1,0) with a radius of 1. Participants suggest that to find z^2, one should take the values of z on the circle and compute their squares, leading to the set {(z, z^2): |z - 1| = 1}. Clarification from a professor is recommended for further understanding.

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.

I'm confused, too. Maybe you're supposed to take the z values on the circle and square them. If that's the case, what you'd be graphing is the set {(z, z^2): |z - 1| = 1}.

If I were you, I'd get clarification from my prof.
