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;

HP-UX COMPATIBILITY

DESCRIPTION
     These functions compute the designated hyperbolic  functions
     for real arguments.

DIAGNOSTICS
     _S_i_n_h and _c_o_s_h return a huge value of appropriate  sign  when
     the correct value would overflow.
