Inverse Trig Functions

Find the angle (arcsin, arccos, arctan) from a known ratio.

Degrees
30.00°
Radians
0.5236

Σ The Formula

θ = arcsin(x)

Real World Examples

Standard Angle
arcsin(0.5) = 30° (or π/6 radians).
Domain Limits
arcsin and arccos are only defined for values between -1 and 1.

# About This Calculator

Inverse Trigonometric Functions (also called 'Arc' functions) do the opposite of standard trig functions. While `sin(θ)` gives you a ratio, `arcsin(ratio)` gives you the original angle θ.

Domains:

  • arcsin(x) & arccos(x): Domain is [-1, 1].
  • arctan(x): Domain is all real numbers.

How To Use

  1. Select the function (Asin, Acos, Atan).
  2. Enter the **Value** (ratio).
  3. The result shows the angle in both **Degrees** and **Radians**.
