Determine two coterminal angles positive and negative

The video tutorial explains how to determine coterminal angles, both positive and negative, for a given angle of -45 degrees. It covers the concept of coterminal angles, which share the same initial and terminal sides, and demonstrates how to calculate these angles by adding or subtracting 360 degrees. The tutorial also addresses potential errors in calculations and provides a step-by-step guide to finding the smallest positive and negative coterminal angles.
