The Complex Plane
Imaginary numbers arise frequently in mathematics, but in order to do much with them we need to know more about the complex plane and the rectangular form of complex numbers. The complex plane is a medium used to plot complex numbers in rectangular form, if we think as the real and imaginary parts of the number as a coordinate pair within the complex plane.

The following diagram shows how complex numbers can be plotted on a Complex Plane. Scroll down the page for more examples and solutions. Introduction to complex numbers, Imaginary and complex numbers
