Core Function ACos
From Sputnik Wiki
ACos( <expression> )
Contents |
Description
Calculates the arcCosine of a number.
Parameters
expression
Any value between -1 and 1 inclusive.
Return Value
Returns the trigonometric arccosine of expression. Result is in radians.
Remarks
ACos(x) is mathematically defined only for -1 < x < 1, so ACos tends to return NaN for other values of x.
Example
$x = ACos(0.5) $radToDeg = 180 / @PI $y = ACos(-1) * $radToDeg println( "Value is: $y " ) ;arcCosine of -1 returns 180°
