Application Files
A collection of Mathcad applications in a range of disciplines.
File sizes are listed at the end of file descriptions, along with the version of
Mathcad required. Note that older-version files can be read with newer
versions of Mathcad and that Mathcad 3.1 files can be read with either the
Macintosh or Windows Mathcad 3.1.
If you are using the MathSoft Mathbrowser, you'll be able to view most of the
following Mathcad files directly (up through Mathcad 5.0). If you are using
another Web browser, note that links will take you to the ASCII readout of
Mathcad files unless you have configured your browser to use Mathcad as a
viewer/helper application. For information about how to do this, look here.
If you'd be willing to contribute a document, please send it to
appmath@mathsoft.com. Please uuencode any Mathcad file you send (to ensure
its integrity). You may alternatively place such files in our /pub/contrib
directory via anonymous ftp, making certain you select the binary mode for the
transfer.
The files listed here have not been tested, approved, or in any way endorsed by
MathSoft, Inc. or Adept Scientific; unfortunately, we cannot provide
technical support on these files.
