Homework Statement
I'm given two circles in the complex plane. [itex]|z|=1[/itex] and [itex]|z-1|=\frac{5}{2}[/itex]. The goal is to find a "Linear Fractional Transformation" or Mobius Transformation that makes these two circles concentric about the origin.
Homework Equations
[itex]w=f(z)=\frac{az+b}{cz+d}[/itex]
The Attempt at a Solution
From other examples I've seen of this, people typically pick three points on the curve they are trying to transform and 3 points on the curve they are trying to transform too. They then use the equation above and solve for the coefficients.
The problem for me is that I don't know exactly what I'm mapping my plane too. I don't know what w values correspond with what z values. All I know is that I am trying to make the two circles concentric about the origin.
Please please please don't beat around the bush. I have a final in 2.5 hrs that may have this material on it. We didn't cover it in class so I think it's ridiculous that it may be on the final, but it was on the practice final so I need to learn it now. You don't have to just give me the answer, but please at least just tell me how to get it. I can take it from there
