Arccos Calculator
Arccos Calculator Introduction
The arccosine function (arccos) is the inverse function of the cosine function. Given a number between -1 and 1, the arccos function returns the corresponding angle value (in radians or degrees).
Mathematical properties:
- Domain: [-1, 1]
- Range: [0, π] radians or [0°, 180°]
- The function is monotonically decreasing
Example values:
- arccos(1) = 0° or 0 radians
- arccos(0.5) ≈ 60° or π/3 radians
- arccos(0) = 90° or π/2 radians
- arccos(-1) = 180° or π radians
