How to determine one positive and one negative coterminal angle

The video tutorial explains the concept of initial and terminal sides of angles, focusing on how to determine coterminal angles. It covers the calculation of both positive and negative coterminal angles by adding or subtracting 360 degrees. The tutorial provides examples to illustrate the process and emphasizes understanding the direction of angle measurement.

Explain the process of finding both positive and negative coterminal angles.
