Learning to find the reference angle by using coterminal angle

The video tutorial explains how to work with negative angles, specifically focusing on the clockwise direction and how to find coterminal angles. It guides viewers through calculating the smallest positive coterminal angle by adding 360 degrees and determining reference angles in Quadrant 3. The tutorial emphasizes the importance of using coterminal angles correctly to avoid common mistakes.
