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

For a circle of radius 1, arcsin and arccos are the lengths of actual arcs determined by the quantities in question. Several notations for the inverse trigonometric functions exist.

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, …

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 …

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

Jul 23, 2025 · The inverse of the cosine function, the arccosine function (arccos or cos⁻¹), returns the angle whose cosine is a given value. Its definition spans values from -1 to 1, and its output …

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).

Oct 29, 2025 · Learn how to draw and interpret the arccos graph. Understand its shape, range, and relationship to cosine in this clear guide to inverse trigonometric functions

No. Cosine takes an angle and gives a y-value on the unit circle. And arccosine is the opposite: it takes a y-value on the unit circle and tells you the required angle to get that y-value. So, …
