Solving trigonometric equations with multiple angles

The video tutorial explains how to solve trigonometric equations by isolating the trigonometric function and solving for the variable. It covers the relationship between secant and cosine, using the unit circle to find angles where cosine equals 1/2, and extends solutions beyond the interval of 0 to 2π by adding coterminal angles. Finally, it demonstrates solving for X in multiple angle equations by dividing and finding general solutions.
