Solving trigonometric equations with multiple angles

The video tutorial explains how to solve sine equations, specifically when sine of 2X equals -sqrt(3)/2. It begins by identifying angles on the unit circle where sine equals -sqrt(3)/2, then addresses solving for 2X instead of X. The tutorial continues by finding all solutions using coterminal angles and concludes with the final solution for X.
