arcsindarcsine 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
