How to find all the solutions to a trigonometric equation

The video tutorial explains solving a trigonometric equation by applying inverse operations and understanding the unit circle. It covers finding solutions within a specific range and generalizing them to all real solutions using coterminal angles. The importance of considering both positive and negative square roots is emphasized, and the process of rationalizing the denominator is demonstrated.
