Whats the difference in their solutions and how you find it?

The video tutorial explains how to solve trigonometric equations using algebraic, graphical, and unit circle methods. It covers three examples: solving 2sin²θ - 1 = 0, 2sin(2θ) = -1, and sin(θ/2) = 1/2. Each example demonstrates different techniques, including inverse operations, substitution, and understanding the unit circle. The tutorial emphasizes finding solutions within specific intervals and for all possible values.
