COS(3) BSD Programmer's Manual COS(3)
cos, cosf - cosine function
#include <math.h> double cos(double x); float cosf(float x);
The cos() and cosf() functions compute the cosine of x (measured in radi- ans). A large magnitude argument may yield a result with little or no significance. For a discussion of error due to roundoff, see math(3).
The cos() function returns the cosine value.
