      NAME
           sinh, cosh, tanh - hyperbolic functions

      SYNTAX
           #include <math.h>

           double sinh (x)
           double x;

           double cosh (x)
           double x;

           double tanh (x)
           double x;

      DESCRIPTION
           Sinh, cosh and tanh return respectively the hyberbolic sine,
           cosine and tangent of their argument.

      DIAGNOSTICS
           Sinh and cosh return HUGE when the correct value would
           overflow, and set errno to ERANGE.

           These error-handling procedures may be changed with the
           function matherr(3M).

      SEE ALSO
           matherr(3M).
