SINH(3M)
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.
