content: I am a fan of traditional theorem-proof exposition, and this Ostebee-Zorn text demonstrates why. This book attempts to make calculus easy to understand, but the only result is that it is impossible to follow. Essential concepts are buried deep within piles of verbiage, and the examples skip important steps making them hard to follow. Add to that the large number of typos and errors in the solutions manual. As a teaching assistant, I have had strong mathematics students who could not understand this book and whose knowledge of calculus suffered as a result. With so many quality calculus textbooks on the market, it is hard to understand why a school would choose to use this unsuccessful experiment.
