This textbook for the undergraduate vector calculus course presents a unified treatment of vector and geometric calculus. It is a sequel to my *Linear and Geometric Algebra*. That text is a prerequisite for this one.

Linear algebra and vector calculus have provided the basic vocabulary of mathematics in dimensions greater than one for the past one hundred years. Just as geometric algebra generalizes linear algebra in powerful ways, geometric calculus generalizes vector calculus in powerful ways.

Traditional vector calculus topics are covered, as they must be, since readers will encounter them in other texts and out in the world.

The book can be used for self study by those comfortable with the theorem/proof style of a mathematics text.

## Fourth Printing

The fourth printing has no major changes.
It corrects all errors known to me in the third printing.
The font size is larger, to match that of *Linear and Geometric Algebra*.

## What People Are Saying

From a review of *Linear and Geometric Algebra*:

"Alan Macdonald's text is an excellent resource if you are just beginning the study of geometric algebra and would like to learn or review traditional linear algebra in the process. The clarity and evenness of the writing, as well as the originality of presentation that is evident throughout this text, suggest that the author has been successful as a mathematics teacher in the undergraduate classroom. This carefully crafted text is ideal for anyone learning geometric algebra in relative isolation, which I suspect will be the case for many readers."

— Jeffrey Dunham, William R. Kenan Jr. Professor of Natural Sciences, Middlebury College

## Computer Exercises

**GAlgebra.** The computer exercises in the book use GAlgebra,
a Python module written by Alan Bromborsky.
It is available here.
GAlgebra is cross-platform (Linux, PC, Mac), with all components freely available on the web.
The software is no longer available at this page.

**Notebook.** GAlgebra works in Jupyter (formerly IPython) notebooks.
Output is typeset in beautiful LaTeX.

GAlgebraPrimer.pdf contains instructions for installing and using the module. It also downloads with the module. Updated 7/9/17.

The book promises these files: VAGC Instructor, URLs.txt, Symbols.pdf, Template.py.
