Undergraduate Lecture Notes in Physics (ULNP) publishes authoritative texts covering topics throughout pure and applied physics. Each title in the series is suitable as a basis for undergraduate instruction, typically containing practice problems, worked examples, chapter summaries, and suggestions for further reading.
ULNP titles must provide at least one of the following:
An exceptionally clear and concise treatment of a standard undergraduate subject.
A solid undergraduate-level introduction to a graduate, advanced, or non-standard subject.
A novel perspective or an unusual approach to teaching a subject.
ULNP especially encourages new, original, and idiosyncratic approaches to physics teaching at the undergraduate level.
The purpose of ULNP is to provide intriguing, absorbing books that will continue to be the readers preferred reference throughout their academic career.

Preface
Engineering is like dancing; you dont learn it in a darkened lecture hall watching slides: you learn it by getting out on the dance floor and having your toes stepped on.
Professor Jack Alford (19202006), cofounder of the Engineering Clinic at Harvey Mudd College, who hired the author in 1971 as an assistant professor. The same can be said for doing definite integrals.
To really appreciate this book, one dedicated to the arcane art of calculating definite integrals, it is necessary (although perhaps it is not sufficient) that you be the sort of person who finds the following question fascinating, one right up there in a fierce battle with a hot cup of coffee and a sugar donut for first place on the list of sinful pleasures:
without actually calculating x, show that
if
it then follows that
