ACOS

Description

Returns the inverse cosine of a value, in radians.

Sample Usage

ACOS(0)

ACOS(A2)

ACOS(1)

Syntax

ACOS(value)

• value - A value between -1 and 1, inclusive for which the inverse cosine is calculated.

Notes

• The DEGREES function can be used to convert the result of ACOS into degrees.

• Because cosine is periodic, there are multiple solutions to the inverse. ACOS returns the solution between 0 and Pi.

Step 1: To use the ACOS Formula, simply begin with your edited Excellentable:

Step 2: Then begin typing the ACOS formula in the area you would like to display the outcome: 

Step 3: By adding the values you would like to calculate, Excellentable generates the outcome:
