What is the complex number plane

The video tutorial introduces the concept of the complex number plane, starting with a review of Cartesian coordinates. It explains how to plot points on the X and Y axes and then transitions to graphing complex numbers using the A and BI axes. The A axis represents real numbers, while the BI axis represents imaginary numbers. The tutorial concludes with an overview of the complex plane, highlighting how to describe complex numbers in the form A + BI.

What is the significance of the Cartesian coordinates in relation to the complex number plane?

Explain how the imaginary part (BI) affects the position on the complex plane.
