Hello K,

The Mathcad program itself sells for several hundred dollars. The PTC
Company publishes this program, and it alone is quite expensive. The disk in
my book is part of a promotional plan by PTC to encourage the sales and use
of the Mathcad program. Even if the book itself is of no value, which I do
not believe, the Mathcad is of considerable value. Go to www.PTC.com if you
want to learn more about Mathcad.

I have Mathcad 4.0; would it be sufficient? If so, is the book available
separately?
