ArchimedeanSpiral-center-inverse

The product of the distance from the green point (the center of the Archimedean spiral) to the blue point (on the Archimedean spiral), and the distance from the green point to the red point (on the inverse curve) is constant (and equal to the square of the radius of the green circle).
