Arccos calculator

Enter the cosine value, select degrees (°) or radians (rad) and press the = button. In order to calculate cos(x) on the calculator : Enter the input angle. Select angle type of degrees (°) or radians (rad) in the combo box. Press the = button to calculate the result.

An easy to use online calculator to calculate the arc cosine function arccos (x).

Tho outputs are presente in raddians and degrees.

Online calculator for arbitrary sized numbers, vectors and matrices.

Function: Inverse cosine ( arccos ), Category: Trigonometry. The inverse of cosine is called as arccos (cos -= acos). It is also known as acos or inverse cosine.

This online calculator can be used to find the inverse cosine value of an angle. The Arccos Calculator is also called the Inverse Cosine Calculator, as it is the inverse of the cos . Free Online Inverse Cosine Calculator works in degrees or radians, plus draws triangle. Sz and choose precalculus tab at th. Note: Fill in one box to get in the other box by clicking Calculate button.

Data should be separated by coma (,), space ( ), tab, or in separated lines. The arccosine function is the inverse functions of the cosine function. ACOS (x) returns the arccosine of x. The result is an angle expressed in radians.

To convert from radians to degrees, use the . The graphing calculator is programmed to graph arcsin(x), arccos (x) and arctan(x ) as functions (thus the domains are limited to ensure that the graphs pass the vertical line test for functions). Arccos(x), cos -(x), inverse cosine function. It gives me that decimal, that strange number.

Refer to the graph to the right where the dots are the desired values. The second value, called θ, is found by using the symmetry of the Arccos curve. Notice that the two blue arrows in the graph . For every trigonometry function, there is an inverse function that works in reverse.

On some calculators the arccos button may be labelled acos , or sometimes cos -1. So the inverse of cos is arccos etc. When we see arccos x, we understand it as the angle . When using scientific calculators for tests, memorize the locations of keys such as the arcsin beforehand. Method 2: Entering the ratio of the .
