Determining coterminal angles by adding and subtracting 2pi

The video tutorial explains how to find the smallest positive and negative coterminal angles using the example of 7π/11. It begins by introducing the concept of coterminal angles and the specific angle in question. The tutorial then describes the algebraic method to find these angles by adding and subtracting 2π, ensuring common denominators. Finally, it simplifies the results to find the coterminal angles of 29π/11 and -15π/11.
