Here we have a text that is very nice for the audience for which it was intended. It is meant as a last course in real analysis for those intending to go into teaching, giving them that necessary layer of knowledge above calculus so that they can teach calculus well and with confidence. At the author’s school, Appalachian State University, the course is called “Analysis for teachers”.

It is short, a mere 262 pages, but includes everything that should be included and then some: its historical material is valuable and included some items that were new to me. There are good exercises, though they appear only at the end of the five chapters, making the assignment of daily homework a little harder. I will refrain from listing its contents: a summary is here.

The writing is good, the author includes many references, the pictures are pretty, and the numerous italicized exhortations to students (e.g., “Verify this!”) may inspire some useful work.

This is an admirable text that I hope will be widely used.

Because we don’t want the author to get a swelled head, I will exercise my reviewer’s prerogative of pointing out unimportant mistakes: on page 119, “l’Hôpitals Rule” appears three times; to make up for the lack of apostrophes, “the Bernoulli’s” is on page 97. And poor L’Hôpital doesn’t get an entry in the index.

Look at this book! You’ll like it.

Woody Dudley learned his real analysis from Richard Goldberg’s text, published circa 1957. It was good too.
