arcsind  arcsine function (degrees) 
Syntax  arcsind (r : real) : real

Description  The arcsind function is used to find the arc sine of an angle given in degrees. For example, arcsind (0.5) is 30.

Example  This program prints out the arcsine of values from 1 to 1 in degrees.
for i : 4 .. 4 const arg := i / 4 put "Arc sine of ", arg, " is ", arcsind (arg), " degrees" end for 
Execute  
See also  the arccosd and arctand functions for calculating arccosine and arctangent the arcsin function which finds the arc sine of a value with the result given in radians. (2p radians are the same as 360 degrees.) See also predefined unit Math.
