sin(30°) = 0.5, cos = 0.866025

  • sin(30°) = 0.5, cos = 0.866025.
  • The equivalent angle in [0°, 360°) is 30.00°, placing it in Quadrant I (0-90°).
  • Pythagorean identity check: sin² + cos² = 1.000000 (should be 1.000000).
  • tan(30°) = 0.57735, so the slope of the corresponding radius is 0.57735.
