Math & Algebra Tool
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
- Select the function (Asin, Acos, Atan).
- Enter the **Value** (ratio).
- The result shows the angle in both **Degrees** and **Radians**.
