NAME
       cosh(),	coshf(),  coshl(),  coshw(), coshq() - hyperbolic cosine func‐
       tions

SYNOPSIS
   HP Integrity Server Only
DESCRIPTION
       returns the hyperbolic cosine of x.

       is a version of it takes a argument and returns a result.

   Integrity Server Only
       is a version of it takes a argument and returns a result.

       is an version of it takes an argument and returns an result.

       is equivalent to on HP-UX systems.

USAGE
       To use these functions compile either with the default option  or  with
       the and the options.

       To use (for Integrity servers) or compile also with the option.

       To use any of these functions, make sure your program includes and link
       in the math library by specifying on the	 compiler  or  linker  command
       line.

       For more information, see the at the following site:

RETURN VALUE
       returns 1.

       If x returns +INFINITY.

       If x is NaN, returns NaN.

       returns	infinity  (equal  to in lieu of a value whose magnitude is too
       large, and raise the overflow and inexact exceptions.

       When it raises no other exception, whether raises the inexact exception
       is unspecified.

ERRORS
       If the correct value would overflow, sets to [ERANGE].

   Integrity Server Only
       HP-UX  functions	 on Integrity servers do not set by default.  For set‐
       ting, compile with the option.
