NAME

sinh, cosh, tanh − hyperbolic functions

USAGE

#include <math.h>
 
double sinh(x)
 
double cosh(x) double x;
 
double tanh(x) double x;

DESCRIPTION

These functions compute the specified hyperbolic functions for a real x. 

DIAGNOSTICS

Sinh and cosh return +/- HUGE when the correct value would overflow.
