I think it assumes radians instead of degrees. A quick fix is to convert to radians before the call.
Actually, cos is a function included in math.h, and uses radians, so it would be prototyped with int.
To convert degrees to radians, just multiply degrees by pi, then divide by 180. Or, to save processing time, multiply it by a constant you make called PI180, than holds pi/180

The prototype is double
For example:
double cos (double x);
// x is the angle in radians
What do you mean:
" Is there an alternative to the default functions?"?
One alternative is sin/cos tables, a sliderule, paper and pencil.
JUST JOKING!!!
In theory, there is no difference between practice and theory.
In practice, there is.
