Tutorial - Graphing complex numbers ex 1, 2i

The video tutorial explains how to graph imaginary numbers on a complex plane. It introduces the concept of a complex plane with real and imaginary axes, similar to Cartesian coordinates. The tutorial demonstrates plotting complex numbers, specifically focusing on numbers with no real component, like 2I. The explanation includes how to interpret the axes and plot points accordingly.

How do positive and negative values appear on the imaginary axis?

What is the general form of complex numbers and how does it relate to graphing?
