Example Calculations

Example 1: Angle = 30°

  • Sin: sin(30°) = 0.5000
  • Cos: cos(30°) = 0.8660
  • Tan: tan(30°) = 0.5774
  • Cot: cot(30°) = 1.7321

Example 2: Angle = 90°

  • Sin: sin(90°) = 1.0000
  • Cos: cos(90°) = 0.0000
  • Tan: tan(90°) = ∞ (undefined)
  • Cot: cot(90°) = 0.0000

Example 3: Angle = 0°

  • Sin: sin(0°) = 0.0000
  • Cos: cos(0°) = 1.0000
  • Tan: tan(0°) = 0.0000
  • Cot: cot(0°) = ∞ (undefined)

These examples show how the calculator handles both regular and edge cases accurately, making it a reliable tool for all angle calculations.
