How to determine two coterminal angles for a negative angle

The video tutorial explains how to find coterminal angles, both positive and negative, by adding or subtracting 360 degrees from a given angle. It starts by defining coterminal angles and their properties, then demonstrates the calculation of the smallest negative and positive coterminal angles using a given angle of -56 degrees. The tutorial emphasizes understanding the concept of coterminal angles having the same initial and terminal sides.

Explain the process of finding the smallest negative coterminal angle.
