Arccos Calculator Online

Online arccos calculator, inverse cosine function calculator, can calculate angle from arccos(x) value.
The arc cosine arccos(x) function is the inverse function and inverse operation of cos(x), such as
arccos(x) = cos⁻¹(x) =y

arccos(1) = cos⁻¹(1) = 0°
arccos(0.5) = cos⁻¹(0.5) = 60°
arccos(0) = cos⁻¹(0) = 90°
