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

These functions compute the designated hyperbolic functions for real arguments. 

DIAGNOSTICS

These functions handle exceptional arguments in the spirit of IEEE standard P754 for binary floating point arithmetic.  Thus sinh and cosh return infinity on overflow.
