ASin( <expression> )
Contents |
Description
Calculates the arcsine of a number.
Parameters
expression
Any value between -1 and 1 (inclusive).
Return Value
Returns the trigonometric arcsine of expression. Result is in radians.
Remarks
ASin(x) is mathematically defined only for -1 < x < 1, so ASin tends to return NaN for other values of x.
Example
$x = ASin(0.5) $radToDeg = 180 / @PI $y = ASin(1) * $radToDeg println( "Value is: $y " ) ;arcsine of 1 returns 90°
