Sine – Quick Cheat Sheet

• Degrees → Radians: rad = deg × π / 180
• Radians → Degrees: deg = rad × 180 / π
• Normalization: angles wrap every 360° (or 2π radians).
• Exact values (unit circle):
  • sin(0)=0, sin(π/6)=1/2, sin(π/4)=√2/2, sin(π/3)=√3/2, sin(π/2)=1
  • Signs depend on quadrant (I:+, II:+, III:−, IV:−).
• Precision: Use “Decimal places” to format the approximate result (0–12).
