cosd

#cosd

##Syntax cosd (r : real) : real

##Description The cosd function is used to find the cosine of an angle given in degrees. For example, cosd (0) is 1.

##Example This program prints out the cosine of 30, 60, 90, up to 360 degrees.

    for i : 1 .. 12
        const angle := i * 30
        put "Cos of ", angle, " is ", cosd (angle)
    end for

##See also the sind.html and tand.html functions for calculating sine and tangent.

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