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.

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 \([0,π]\)
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.
16 wrz 2022 · The inverse cosine function \(y=\cos^{-1} x \) (sometimes called the arc cosine and denoted by \(y=\arccos\;x\)) can be determined in a similar fashion. The function \(y=\cos\;x \) is one-to-one over the interval \([0,\pi] \), as we see in the graph below:
Inverse Cosine. Author: dfreeston. Topic: Cosine. Inverse functions can be found algebraically by interchanging x and y in the function definition and then making y the subject of the equation. They can also be found graphically by reflecting the graph of the function in the line y = x.
Inverse Cosine Function Graph. The inverse of the cosine function is also called as “Arc Function” and is denoted as Arccos or Arccosine (acos). The graph of Arccosine function is given below; Where y=cos-1 x(arccosine of x) Domain of Inverse Cosine Function. The domain and range of arccosine function is denoted as; Domain: −1 ≤ x ≤ 1
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.
