Synopsis:
    #include <math.h>
    double sinh( double x );

Description:
    The sinh function computes the hyperbolic sine of x.  A range error
    occurs if the magnitude of x is too large.

Returns:
    The sinh function returns the hyperbolic sine value.  When the argument
    is outside the permissible range, the  matherr function is called.
     Unless the default  matherr function is replaced, it will set the
    global variable  errno to  ERANGE, and print a "RANGE error" diagnostic
    message using the  stderr stream.

Example:
    #include <stdio.h>
    #include <math.h>

    void main()
      {
        printf( "%f\n", sinh(.5) );
      }

    produces the following:

    0.521095
