Homework Statement
Let have the problem to find the complex generalized cirlce of radius r
Homework Equations
[tex]|z-c|^2 = r^2 [/tex]
The Attempt at a Solution
hvor r is the radius and c the center..
by expanding the above
[tex]z\overline{z} - z\overline{c} - \overline{z}c + c\overline{c} -r^2 = 0[/tex]
I know that if I multiply with a real number when I can get a more pretty expression, but what as is my motivation to do this?
