Determine two coterminal angles positive and negative

The video tutorial explains how to determine the smallest and largest coterminal angles for a given angle, Theta equals -15π/2. It discusses the concept of coterminal angles, which share the same initial and terminal sides, and demonstrates how to find these angles by adding or subtracting 2π. The tutorial uses sketches to visualize negative angles and explains the process of finding the smallest coterminal angle in both positive and negative directions, concluding with the results of -3π/2 and π/2 as the smallest coterminal angles.
