About Arcsine (arcsin)

In trigonometry, the arcsine is the inverse function of the sine function. It calculates the angle whose sine is a given number.

Domain and Range

The domain (input) of arcsin(x) is [-1, 1]. The range (output) is [-90°, 90°] or [-π/2, π/2] radians.

Notation

arcsin(x) can also be written as sin⁻¹(x) or asin(x).

Common Values

  • arcsin(0) = 0° (0 rad)
  • arcsin(0.5) = 30° (π/6 rad)
  • arcsin(1) = 90° (π/2 rad)
  • arcsin(-1) = -90° (-π/2 rad)

Applications

  • Finding unknown angles in right-angled triangles
  • Solving trigonometric equations
  • Physics and engineering calculations involving angles
