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.
