Arccosine (Arccos) - Definition, Examples, Graph | Arccos x
Arccosine Definition. In a right-angled triangle, the cosine of an angle (θ) is the ratio of its adjacent side to the hypotenuse. i.e., cos θ = (adjacent side) / (hypotenuse). Then by the definition of arccosine, θ = cos -1 [ (adjacent side) / (hypotenuse) ] .
Arccos Calculator to calculate arccos(x)
Use this arccos calculator to easily calculate the arccosine of a number. Supports input of either decimal numbers (e.g. 0.5, -0.5) or fractions (e.g. 1/2, -1/2).
Inverse trigonometric functions - Wikipedia
In mathematics, the inverse trigonometric functions (occasionally also called antitrigonometric, [1] cyclometric, [2] or arcus functions [3]) are the inverse functions of the trigonometric functions, under suitably restricted domains.
Arccos - Math.net
Arccosine, written as arccos or cos -1 (not to be confused with ), is the inverse cosine function. Both arccos and cos -1 are the same thing. Cosine only has an inverse on a restricted domain, 0 ≤ x ≤ π.

Inverse Cosine Calculator – Calculate arccos (x)
Cosine -1, also written as arccosine or acos, refers to the inverse cosine function. This function takes a value between -1 and 1 as the input and returns an angle in radians as the output. For example, if cosine (x) = 0.5, then cosine -1 (0.5) = 1.047 radians.
