Learning to determine co terminal angles by subtracting 2pi twice

The video tutorial explains coterminal angles, focusing on their properties and how to find them both graphically and algebraically. It emphasizes finding the smallest positive and negative coterminal angles, using examples to illustrate the process. The tutorial concludes with a confirmation of the calculations.

What is the significance of the angles having the same initial and terminal sides?

Describe how adding or subtracting 2π affects the coterminal angles.
