The first time I encountered analysis was in graduate school taking a course in real analysis. Such a course would teach students, as one friend put it, “how to write a proof.” That was quite true. From this book I found that what I was really taught might better be called scalar analysis because we worked only with scalar functions. It didn’t occur to me that the same analysis techniques of scalars would apply to vector functions. There is much more to analysis than scalars, as this book can attest.

For those of us who seek to expand our experiences, and to learn analysis on vector spaces, this book is a good start. The format is “classic analysis textbook”: definitions; lemmas and proofs; and theorems (sometimes built from lemmas) and proofs. If that appeals to you, you won’t be disappointed.

The authors begin with a review of sets, numbers, and functions. The discussion is basic but it familiarizes the reader to the authors’ notation and is well worth the time. We then explore real numbers, convergent sequences, and linear transformations. It is with linear transformations that we begin to get to vector spaces and functions in vector spaces. I won’t go through the many sections because MAA provides the table of contents, please see the link above.

The book covers all its topics thoroughly and with examples that beautifully illustrate the ideas. For example, the authors define and explain rigid motion, trajectories, and the Frenet formulas (unit tangent vector, unit principal normal vector, and binormal vector) so that we can explore curvature and torsion. As with much of the book, the discussion is theoretical within the text, but the problems provide the reader with concrete insights. The problems take the material to a higher level.

If you haven’t studied these topics in vector spaces before, this book will serve you well.
