Complex Numbers and Their Representations Quiz

Complex Numbers represent points in a two dimensional complex or s-plane that are referenced to two distinct axes. The horizontal axis is called the “______ axis” while the vertical axis is called the “______ axis”

complex number is represented in two forms. 1. Rectangular form 2. Polar Form 3 1.Rectangular form Z = x + jy Where: Z - is the Complex Number representing the Vector x - is the Real part y - is the Imaginary part j - is defined by ______
