The Complex Plane; DeMoivre's Theorem

The Complex Plane; DeMoivre's Theorem

The Complex Plane; DeMoivre's Theorem. The magnitude or modulus of z denoted by z is the distance from the origin to the point ( x , y ). Remember a complex number has a real part and an imaginary part. These are used to plot complex numbers on a complex plane. Imaginary Axis.
