The video tutorial focuses on finding the solution set for a trigonometric equation involving the sine function. It begins by isolating the sine function algebraically and then explores the general solution using the unit circle. The tutorial explains how to account for all possible solutions by considering integer multiples of 2π and alternative angles that yield the same sine value. Finally, it combines these solutions to derive the complete solution set for the equation.
