Sketch the angle then find the reference angle

The video tutorial explains how to find coterminal angles by adding or subtracting 2π. The teacher discusses simplifying angles by removing extra revolutions and introduces the concept of reference angles, using π/3 as an example. The tutorial emphasizes understanding the relationship between angles and the X-axis, providing a clear explanation of how to graph these angles.
