| cos | cosine function (radians) |
| Syntax | cos (r : real) : real
|
| Description | The cos function is used to find the cosine of an angle given in radians. For example, cos (0) is 1.
|
| Example | This program prints out the cosine 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 "Cos of ", angle, " is ", cos (angle)
end for
