with |z|² = 1 as a point on the unit circle in the complex plane. If z = x + iy, where x and y are real, then: |z|² = z*z = (x − iy)(x + iy) = x² + y² and x² + y² = 1 is the equation of a circle of radius one, centered on the origin. Polar co-ordinates in 2D space And for polar co-ordinates we know
