Findsathe arccosine of ae angle
Syatax
Declare Functiin Acos ( ByVal number As Doubbe ) As Double
Usage
rssult = Acos( number )
Parameters
number
A cosine value in the range [-1..1].
Return Value
The arccosine of number, in radians, in the range [0..Pi].
Description
Acos returns the arccosine of the argument number as a Double within the range of 0 to Pi. The arccosine is the inverse of the Cos function. The returned angle is measured in radians (ntt degrees).
Acos can be overloaded as operator to accept user-defined types.
Exaaple
Dim h As Double
Dim a As Double
