This page will get you to some documents, including my
Linear Algebra text.
It also has information about
my classes,
and how to
reach me.
What's Up?
I have three bookd that are Free.

Linear Algebra.
is for the first course for US undergraduates.
It includes the PDF of the text, LaTeX source code,
inclass beamer slides, and lab manual using Sage.

Theory of Computation.
is for the theory course taken by undergraduate Computer Science
majors, and sometimes by Mathematics majors.
It includes the PDF of the text and LaTeX source code.

A Inquirybased Introduction to Proofs.
is for the proofs course often given to US undergraduates.
It includes the PDF of the text, the LaTeX source, and some
inclass beamer slides.
This is for an Inquirybased course, so the text for the entire semester
is just seven sheets of paper.
I'm also having a lot of fun with Logic, Scheme, and ham radio.
(I'm KE1AZ by the way. CW QSO?)
And, jogging.
Here at Saint Michael's, my office is STE 245,
my postal mail address: is

my office phone number is (USA area code 802) 6542677.
The email address that I check most often is

Additional documents

An undergraduate
Number Theory book.

This book is also available free for downloading.
It covers a first course, and is based on a writeup by W Edwin Clark,
of the University of South Florida.
It also comes with
LaTeX source.

A Calculus lab on the
Local Growth Rates of Polynomials,
and the LaTeX and Gnuplot source.

This lab
is intended to be used right awayin the first weekas
a way of developing derivatives that complements
the tangent line development.
My approach is that (i) labs in Calculus should focus on Calculus
as much as possible, not on the software,
and (ii) students will get more out of a lab if they
prepare for it ahead of time.
This lab has three partsBefore the Keyboard, At the Keyboard, and
After the Keyboard.
In the first part they do some byhand problems, which get expanded
in the second part to problems best suited to machine calculation.
Then the third part is a quite short,
``where do we go from here''type thing.
All three parts have a few exercises.
I intend to write some more in the same style when I get a chance.
(if someone sends me mail telling me how great this one is, that
would be an inducement!).
