cos, cosh

Cos calculates the cosine and cosh calculates the hyperbolic cosine of an angle.

#include <math.h>

double cos (double x);

double cosh (double x);

The cosine or hyperbolic cosine.

cos	Returns a PLOSS error if x is large and a partial loss of significance in the result occurs; function sets errno to ERANGE. Prints a TLOSS message to stderr and returns 0 if x is so large that significance in the result is completely lost; function sets errno to ERANGE.
cosh	Returns HUGE_VAL and sets errno to ERANGE if the result is too large.

Note: This function does not return standard ANSI domain or range errors.
