sin

#sin

##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

##See also the cos.html and tan.html functions for calculating cosine and tangent.

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