Syntax

ACos(Value)

Value. This is the cosine of the angle in question. Available values are in the range from -1 to 1.

NOTE. To determine the parameter, specify either the number or the address of the cell where it is located.

It returns the number arccosine.

The arccosine of a number is the angle, the cosine of which is equal to the number. The angle is specified in radians between 0 and Pi value.

Formula	Result	Description
= ACos(A1)	1,2661	The arccosine of the number from the A1 cell expressed in radians. The A1 cell contains the 0.3 number.
= ACos(0.6)	0,9273	The arccosine of the 0.6 number expressed in radians.

NOTE. To convert the result from radians to degrees, use the Degrees feature.
