Mathematics - Trigonometry - Advanced - Unit circle - Unit Circle Values

15 problems: find exact sin/cos/tan values for unit circle angles. Include: standard angles in all 4 quadrants (sin150°, cos225°, tan330°), radian angles (sin(π/3), cos(5π/6)), and finding the angle given values (cosθ=-1/2, θ in Q3 → θ=240°=4π/3). No calculator - exact values only.
