Syntax

@ASin( sine )

Parameters

sine

Return value

angle

Number or number list. An angle, in radians, from -pi/2 through pi/2. This represents an angle between -90 and 90 degrees.

Usage

If the parameter is a list, the function operates on each element of the list, and the return value is a list with the same number of elements.

Examples

  1. This example returns pi/2.
    @ASin( 1 )
  2. This example returns 0.72082 radians (41.3 degrees).
    @ASin ( 0.66 )
  3. This example returns pi/2 and 0.72082 radians in a list.
    @ASin ( 1 : 0.66 )
