    1. The problem statement, all variables and given/known data
    If R is a real number, find the locus of z defined by:


    2. Relevant equations

    3. The attempt at a solution


    Therefore, [tex]x=\frac{1-R^2}{1+R^2}[/tex]

    and [tex]y=\frac{2R}{1+R^2}[/tex]

    I'm unsure what to do now though...
