SINH(3M)																  SINH(3M)

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
       Sinh and cosh return a huge value of appropriate sign when the correct value would overflow.
