Concept

What is Arcsin?

The arcsin function (also known as inverse sine) is the inverse of the sine function. It takes a value between -1 and 1 and returns the angle whose sine is that value.

Definition:
If y = sin(θ), then θ = arcsin(y)
Formula

Arcsin Formula

The arcsin function can be calculated using the following formula:

Formula:
arcsin(x) = θ where -1 ≤ x ≤ 1 and -90° ≤ θ ≤ 90° (or -π/2 ≤ θ ≤ π/2 in radians)
Values

Common Arcsin Values

Special Values

  • arcsin(0) = 0°
  • arcsin(0.5) = 30°
  • arcsin(0.7071) = 45°
  • arcsin(0.8660) = 60°
  • arcsin(1) = 90°

Properties

  • Domain: [-1, 1]
  • Range: [-90°, 90°] or [-π/2, π/2]
  • Odd function: arcsin(-x) = -arcsin(x)
  • arcsin(sin(θ)) = θ for -90° ≤ θ ≤ 90°
