How do you use the unit circle to determine the exact values of sin, cos, and tan for common angles such as 30°, 45°, and 60°?

To determine the exact values of sin, cos, and tan for 30°, 45°, and 60° using the unit circle, locate these angles on the circle. For 30° (π/6), sin(30°) = 1/2, cos(30°) = √3/2, tan(30°) = 1/√3. For 45° (π/4), sin(45°) = cos(45°) = √2/2, tan(45°) = 1. For 60° (π/3), sin(60°) = √3/2, cos(60°) = 1/2, tan(60°) = √3.
