arcsind

#arcsind

##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

##See also the arccosd.html and arctand.html functions for calculating arccosine and arctangent

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