sinh(3) — AIX/RT 2.2.1

     sinh, cosh, tanh

Purpose

     Computes hyperbolic functions.

Library

     Math Library (libm.a)

Syntax

     #include <math.h>

     double sinh (x)                           double tanh (x)
     double x;                                 double x;

     double cosh (x)
     double x;
     Description

     The sinh  subroutine returns  the hyperbolic sine  of its
     parameter.   The cosh  subroutine returns  the hyperbolic
     cosine of its parameter.  The tanh subroutine returns the
     hyperbolic tangent of its parameter.

     The  sinh and  the cosh  subroutines return  HUGE if  the
     correct value overflows.  errno is also set to ERANGE.

     You can use the matherr subroutine to change these error-
     handling procedures.  See "matherr" for details.
