Find the coordinate point of given the angle

The video tutorial explains how to find coterminal angles, using the example of 13π/6. The instructor emphasizes the concept of coterminal angles, which share the same initial and terminal sides, and demonstrates how to calculate them by adding or subtracting 2π. The tutorial simplifies the problem by converting 2π to a common denominator and subtracting it from 13π/6, resulting in π/6. The instructor encourages mental calculation and understanding of coterminal angles to solve similar problems efficiently.
