Returns the arc cosine of an angle specified in radians. The range of the result is 0 to PI radians.

 

To convert angle from radians to degrees use RadiansToDegrees function.

 

Short form name: "Acos"

Syntax:

value = ArcCosine( expression )

 

Parameter:

Description:

expression

Any value or expression that resolves to a valid cosine range -1 to 1

 

Example:

value = ArcCosine( 0 )                         ' Returns 1.570795327
value = ArcCosine( 0.5 )                       ' Returns 1.047197551
value = RadiansToDegrees( ArcCosine( 0.5 ) )   ' Returns 60

Returns:

Arc cosine of expression.
