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 between1
and1
, inclusive for which the inverse cosine is calculated.
Notes
The
DEGREES
function can be used to convert the result ofACOS
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:
