Query: Nice try, bad execution

Some years ago, I bought the first edition of this book because, at first glance, it seemed to present a readable discussion of a very difficult subject. However, as I read further, I realized that the writing is very terse and imprecise. Most annoyingly, it was full of typographical errors.This semester I am working with two students on an independent study project on vibration and sound. We decided to use the second edition of this book as one of our sources. To my complete amazement and dismay, the second edition has at least as many typographical errors as the first edition. It is incredibly frustrating to spend half an hour trying to justify an equation, only to realize that "x" should be "y", or "less than" should be "greater than", or "sin" should be "cos".I can recommend this book only if you know enough about the subject to realize what the authors actually meant to say, despite what is written in the book.
