NAME

sinh, cosh, tanh − hyperbolic functions

SYNOPSIS

#include <math.h>

double sinh (x)
double x;

double cosh (x)
double x;

double tanh (x)
double x;

DESCRIPTION

sinh, cosh, and tanh return, respectively, the hyberbolic sine, cosine and tangent of their arguments. 

SEE ALSO

matherr(3M)

DIAGNOSTICS

sinh and cosh return HUGE (and sinh may return −HUGE for negative x) when the correct value would overflow and set errno to ERANGE. 

These error-handling procedures may be changed with the function matherr(3M).
