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.
Suggestions for instructors (one page).
The latest printing is from January 2021.
There are minor improvements.
The previous printing was from October 2020. I added material on the Helmholtz decomposition. The last part of Section 10.4 was split off into a new Section 10.5. The new section also contains some recently published results about antiderivatives. The new Section 11.4 introduced the differential geometry of manifolds of arbitrary dimension. There were several other small improvements.
I have created a five video YouTube playlist Geometric Calculus, about 53 minutes in all, taken from the book. It is a sequel to my Geometric Algebra playlist. Some knowledge of vector calculus is a prerequisite for the videos, but no knowledge of geometric calculus is assumed. The book assumes no knowledge of vector calculus.
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

GAlgebra. The computer exercises in the book use GAlgebra,
a Python 3 module for symbolic geometric algebra and calculus calculations.
It is cross-platform (Linux, PC, Mac), with all components freely available on the web.
GAlgebra runs in a browser using Jupyter Lab notebooks. Output is typeset in beautiful LaTeX.
GAlgebra was originally written by Alan Bromborsky. It is now under development by the Pythonic Geometric Algebra Enthusiasts (PyGAE). Please contact me with questions or problems.
GAlgebraPrimer. The primer provides instructions for installing and using GAlgebra. The current version is dated 9/22/2020.
The latest errata file is dated Updated January 23, 2019.
Please email me corrections, typos, or any other comments about the book. I will post them here as appropriate.
