This book covers most areas of multivariate calculus. However, certain areas, such as Divergence Theorem, and Fundamental Theorem of Line Integrals is not included in the book. I am told it will be added in later additions though. read more

This book covers most areas of multivariate calculus. However, certain areas, such as Divergence Theorem, and Fundamental Theorem of Line Integrals is not included in the book. I am told it will be added in later additions though.

I found this book very accurate with few errors

I don't imagine this book will need updating anytime soon, as Calculus will not be changing. Any updates will simply be to improve the activities, not the material itself.

The book is very clear and easy to understand. The author specifically avoids any confusing mathematical notation in an attempt to make the material accessible.

The book is very consistent.

This book does an incredibly good job of subdividing the various sections into subsections. The author of the book has his students read certain sections before class, as do I. It is very easy to tell students to read through this section of the book. Each subsection within a section is usually around a page.

I particularly like how one section flows into the next, telling one coherent story.

The online version of this text was very helpful to demonstrate visual elements of the material to the class. With multivariate in particular, the visual elements are complex and hard to draw for those of us with little drawing skill. It was helpful to have various graphs online to demonstrate ideas to the students.

I found no grammatical errors in my using of the book.

The author uses both male and female pronouns where applicable, though pronouns in general are not used often.

I have used this book for Multivariate Calculus and enjoyed it very much. It is important to stick to doing the activities and having students do the preview activities before class. Some students have trouble using this book as a standalone book, as it is very different from what they are used to. It may be helpful to pair it with a more traditional free textbook, such as APEX.

*Active Calculus Multivariable* is the continuation of *Active Calculus *to multivariable functions. The Active Calculus texts are different from most existing calculus texts in at least the following ways: the texts are free for download by students and instructors in .pdf format; in the electronic format, graphics are in full color and there are live html links to java applets; the texts are open source, and interested instructors can gain access to the original source files upon request; the style of the texts requires students to be active learners — there are very few worked examples in the texts, with there instead being 3-4 activities per section that engage students in connecting ideas, solving problems, and developing understanding of key calculus concepts; each section begins with motivating questions, a brief introduction, and a preview activity, all of which are designed to be read and completed prior to class; the exercises are few in number and challenging in nature.
