BEWARE Wrong edition sent, NO correction made

Customer Rating:

We requested the 6th Edition of Precalculus textbook by Sullivan, using an ISBN number for identification. The seller sent the 7th Edition which is NOT the same. I wrote him directly, told him of the error and requested returning the textbook, he responded that it was the correct one and he was not responsible. He suggested that I sell it on Amazon and that was my only recourse. I feel this is unethcial and very poorly handled. I will not purchase another textbook on Amazon after this experience.

Precalculus textbook

Customer Rating:

This is my first time purchasing anything on Amazon.com. I was a bit skeptical and uncertain. I wondered if the book I ordered would arrive and if so, in what condition. I was pleasantly surprised when I received the package in the mail. When I opened it, I was alarmed that the book was in such good condition and everything that was mentioned about it was true. I purchased a few other books which arrived in the time specified that it would arrive and in the condition that was stated in the ad. I have no fear using this site to purchase other materials.

Precalculus	Customer Rating:
Precalculus (8th Edition) is a great textbook. A little on the heavy side (as in the weight of the book, need a wheel barrel to get it around).

Clear and understandable.

Customer Rating:

At the beginning I was a bit worried about the way the book explains the material. It seemed too simple for a book dealing with more complex subjects in math such as functions, trigonometry and analytic geometry. Then again it could be said that this quality is the one that makes the book such a joy to read. Not a single time did I felt lost or confused by the presentation. Most of the graphics and photos do supplement the explanation, and help the reader grasp the information better. One of the highlights, one that perhaps most people will miss, is the simple review questions at the beginning of each section. These little snippets of previous material force the reader to review those concepts that will be essential for further understanding. Every new section in the book is short and clear; thus reducing the amount of explanation, but at the same time maintaining just enough so that the reader will not feel lost in the many formulas and derivations. If this book does not get "5 starts" from my review it is only because it could be more mathematically rigorous by presenting more proofs. But by not doing so it increases the clarity and easy presentation the book possesses - great book well worth the price.

reviews for the 7th edition?

Customer Rating:

why are the reviews for the 6th and 7th edition of this book the same? is there no difference between editions, such that reviews for the 6th should be kept for the 6th. the 7th edition might have changes that could cause some to review/change a viewpoint about its content. maybe at the core they are the same book/method, but it is overall a different book and the reviews should be kept edition specific. it is my opinion that amazon will not post this as it obviously not a review, but it my contention that the 8 posted are not reviews of this edition, either. why are they posted?
