Sin( <expression> )
Contents |
Description
Returns the sine of the specified angle.
Parameters
expression
Value in radians.
Return Value
Returns the trigonometric sine of number.
Remarks
1° = pi / 180 radians.
Example
$Param = 30.0; $Result = sin ($Param* @PI / 180.0); print("The sine of $Param degrees is $Result."); $x = Sin(@PI / 4.0); println($x); // returns 0.707106781186547 which you should recognize as sqrt(2)/2 $degToRad = @PI / 180.0; $y = Sin(90.0 * $degToRad); println($y); // sine of 90°
