Different representations of polar points with negative radius and angle

The video tutorial explains how to find coterminal angles by adding or subtracting 2π. It covers graphing angles, the impact of a negative radius, and how it reflects the angle about the origin. The tutorial also discusses reference angles and demonstrates finding points using radius and angle, highlighting the possibility of multiple solutions.

How can you graph the angle -7π/6 based on the information provided?

What is the significance of the reference angle in relation to the original angle?
