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;

       These functions compute the designated hyperbolic functions for real arguments.

ERROR (due to Roundoff etc.)
       Below 2.4 ulps; an ulp is one Unit in the Last Place.

DIAGNOSTICS
