    SINH(3M)	    UNIX Programmer's Manual		 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.

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

    DIAGNOSTICS
         Sinh and cosh return the reserved operand on a VAX if the
         correct value would overflow.
