Query: Jello has more substance.

The first thing you notice about this book is that it is over 1300 pages long with nicely formatted text, pretty diagrams, lots of exercises and a little math trivia.Dig a little deeper and you will find yourself staring at pretty pages for days, trying to figure out the missing, or parts of, proofs that were assumed. There are very few proofs in this book and the ones present are in shorthand with chunks missing.This may be acceptable for the "thank-you-laude" engineering crowd but to those interested in understanding what's going on under-the-hood, it's like putting a jigsaw puzzle together.After a year of flipping through the pages of this error-laced tome, I have finally put this glorified recipe book to rest. As of next semester, I will be using a real calculus book: Spivak.The two stars are for effort; not substance.
