sinsine function (radians)

Syntax   sin ( r : real ) : real

Description   The sin function is used to find the sine of an angle given in radians. For example, sin (0) is 0.

Example   This program prints out the sine of p/6, 2p/6, 3p/6, up to 12p/6 radians.

        const pi := 3.14159
        for i : 1 .. 12
            const angle := i * pi / 6
            put "Sin of ", angle, " is ", sin ( angle )
        end for

the sind function which finds the sine of an angle given in degrees. (2p radians are the same as 360 degrees.)
