SUMMARY
The locus of z defined by the equation z=\frac{1+iR}{1-iR} for real number R is determined to be a unit circle in the complex plane. By simplifying the expression, it is shown that the real part x=\frac{1-R^2}{1+R^2} and the imaginary part y=\frac{2R}{1+R^2} lead to the conclusion that |z|=1. This indicates that all values of z lie on the unit circle, confirming that the locus is indeed a circle with a radius of 1 centered at the origin.
