arcsin

#arcsin

##Syntax arcsin (r : real) : real

##Description The arcsin function is used to find the arc sine of a value. The result is given in radians. For example, arcsin (0.5) is p / 6.

##Example This program prints out the arcsine of -1 through 1 in radians.

    for i : -4 .. 4
        const arg := i / 4
        put "Arc sine of ", arg, " is ",
            arcsin (arg), " radians"
    end for

##See also the arccos.html and arctan.html functions for calculating arccosine and arctangent.

the arcsind.html function which finds the arc sine of a value with the result given in degrees. (2p radians are the same as 360 degrees.)
