Finding two coterminal angles both negative

The video tutorial explains coterminal angles, which share the same initial and terminal sides. It covers how to find coterminal angles by adding or subtracting 2π, and demonstrates this with both positive and negative directions. The tutorial also includes calculations using fractions to find these angles and provides a graphical representation to visualize their positions on the unit circle.

What are coterminal angles and how can they be identified?

Explain how adding or subtracting 2π affects the position of an angle.

Describe the process of finding coterminal angles using a specific example.

How do you convert an angle expressed in radians to find its coterminal angles?

What is the significance of the initial and terminal sides of an angle in determining coterminal angles?

Illustrate how to add and subtract fractions when finding coterminal angles.

Discuss the relationship between angles that have the same terminal side.
