Online arccos (x) calculator. Inverse cosine calculator. Enter the cosine value, select degrees (°) or radians (rad) and press the = button.

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. …

What is Arccosine Formula? In a right triangle, if θ is one of the acute angles, then cos θ = (adjacent)/ (hypotenuse). Then θ = arccos ( (adjacent)/ (hypotenuse). This is the formula of arccosine (or arccos).

Definition of the arccos function in trigonometry. The inverse of the cosine function. The angle whose cosine is a given number.

If you know the three sides of a triangle, and you'd like to find any of the triangle's angles, you'll need to use arccos: find everything about this law at our law of cosines calculator.

ArcCos [z] gives the arc cosine cos -1 (z) of the complex number z.
