|cosd||cosine function (degrees)|
|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 and tand functions for calculating sine and tangent.|
the cos function which finds the cosine of an angle given in radians. (2p radians are the same as 360 degrees.)
