Example:
the asin of .225

Example:
sin(asin(.5))

Example:
asin(pi/4 - sin(myAngle))

Parameters:
number: A number between -1 and 1, or an expression that evaluates to such a number.

The result: The result of the <asin> <function> is <return|returned> in <radian|radians>. To get this result in <degree|degrees>, use the following <custom function>:.

Returns: The <asin> <function> <return|returns> a number between -pi/2 and pi/2.

Description:
Use the <asin> <function> to find the arc sine of a number.

The arc sine of <number> is an angle whose sine is equal to <number>. In other words, <asin> is an <inverse> of the <sin> <function>.

  function asinInDegrees theMagnitude
    return asin(theMagnitude) * 180 / pi
  end asinInDegrees
