Elon;
Yes to both questions. MathCAD allows you to type in equations as they
actually appear; the MathCAD page looks just as it would if it were
printed in a book. The equations or variables can be edited and their
effects on the numerical results or on a graph can be seen instantly.
Excel gets messy when you start to get into exponents, roots, complex
math, etc. It is good for what it was intended for-- business
applications that needed spreadsheets. MathCAD is intended for
scientific & engineering.
I can e-mail an Acrobat file showing what a MathCAD page looks like.
Unfortunately I can't attach one to be sent over this server.
BTW, earlier versions of MathCAD were far more reasonably priced. I
found my personal copy on eBay.

Dave & Neil thanks for the book title.
What is interesting is you both endorse MathCad which is a strong
affirmation of the software. So my question is; since MathCad is fairly
expensive and Excel essentially "free", since it is included in "most"
(but not all) MS Office suites, why would MathCad be favored over Excel?
I have never used MathCad and would be interested in a comparison. Excel
has a fairly robust plotting capability. Although you have to crunch
your formula to get "data-in-a-series", once you do that the Excel plots
are very nice. Does MathCad have more flexibility (or is it easier) to
do plotting? -Elon
