Inverse cosine is used to determine the measure of angle using the value of the trigonometric ratio cos x. In this article, we will understand the formulas of the inverse cosine function, its domain and range, and hence, its graph. We will also determine the derivative and integral of cos inverse x to understand its properties better.

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.
2 sty 2021 · The inverse cosine function \(y={\cos}^{−1}x\) means \(x=\cos\space y\). The inverse cosine function is sometimes called the arccosine function, and notated \(\arccos\space x\). \(y={\cos}^{−1}x\) has domain \([−1,1]\) and range \([0,π]\)
10 paź 2024 · The inverse cosine is the multivalued function cos^ (-1)z (Zwillinger 1995, p. 465), also denoted arccosz (Abramowitz and Stegun 1972, p. 79; Harris and Stocker 1998, p. 307; Jeffrey 2000, p. 124), that is the inverse function of the cosine.
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.
30 lip 2024 · The cos inverse is the inverse of the cosine function (no surprises here). That is, the cos inverse finds the angle that produces a particular cosine value. We denote this function by arccos, and we have the following formula: arccos(x) = y if and only if x = cos(y) for x ∈ [-1, 1].
Learning Objectives. Understand and evaluate inverse trigonometric functions. Extend the inverse trigonometric functions to include the \ (\csc^ {-1}\), \ (\sec^ {-1}\), and \ (\cot^ {-1}\) functions. Apply inverse trigonometric functions to the critical values on the unit circle.
