Understanding the Sine Function

The sine function is a fundamental trigonometric function that takes an angle and returns a value between -1 and 1. In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse.

Formula

sin(θ) = Opposite / Hypotenuse

Examples

  • sin(30°) = 0.5
  • sin(45°) = √2 / 2 ≈ 0.7071
  • sin(90°) = 1
  • sin(0°) = 0

Important Notes

The calculator can handle both degrees and radians. Make sure to select the correct unit based on your input. Remember that 180 degrees is equal to π radians.
