Solving a trigonometric equation by taking the square root of both sides

The video tutorial explains how to solve the equation sine squared of X = 1. It begins by isolating the variable and taking the square root to find sine of X equals plus or minus 1/2. The instructor then uses the unit circle to find specific angles where sine equals these values, identifying solutions between 0 and 2π. The tutorial also covers finding all possible solutions by adding π to the initial solutions, providing a comprehensive strategy for solving such trigonometric equations.
