Summary: I HIGHLY recommend this book!!
Review: After looking at countless Pre-calculus books, and buying 6 other books to help supplement my text and instructor, I was lucky to come across this book. It is by far the easiest and clearest book to follow. The authors take you through the problems and concepts, step-by-step, and the language is in plain-simple English. I was frustrated with this subject until I got this book, but I am now understanding it. It is well written. Do not hesitate to get this book...it's GREAT!

Summary: A great review before you do any University calculus course.
Review: After looking at several Precalculus books, I found this the best for someone with my background - someone who has not done maths since high school (10 years ago) and now have to do some university math subjects. Explanations are clear and concise and the book does not assume any prior knowledge in trig, geometry, functions etc. The reason why this book is so good is the balance it strikes-it does not just summarise the subjects like most precalc books do, but at the same time it does not have all the repetition and wordy explanations of precalc books aimed at high school students.
By the end of this book you have all the assumed knowledge needed for first year Calculus. There are questions throughout the book with solutions AND the solutions have short explanations written next to them as to what was done.
A good ongoing reference for University students for their Precalculus formulas, laws and techniques.

Summary: Full of errors
Review: Although the authors have very clear ways of explaining mathematical processes and procedures, the book contains plenty of errors, some minor, some major.For example, when explaining the relationships between trig expressions (p. 153), it is stated that sin u = 1/cos u; in fact, a sine is the inverse of a cosecant, not a cosine. A simple but important typographical error. On page 131, it is clearly stated that 9pi/4 radians is a coterminal of 7pi/4 radians; they are at righta angles to each other. The authors arrived at this solution using incorrect math, which does not lead me to believe that they are checking their work very well. I have found many more such errors, and I am disappointed with the book. I didn't buy it from Amazon, and I'm taking it back to the store for a refund.

Summary: Excellent
Review: As a mathematician I give 5* to this publication. Everything is well explained, the series of chapters is very logical. I recomend it strongly. The exercises cover and target everything without being numerous.

Summary: Errata-fest
Review: Breifly - there are errata in even the 'Basics' section at the beginning of the book, which is the elementary algebra review.
The cover of the book boasts, "Over two million copies sold". Well, if that's the case, then there has been over $35.9 million dollars wasted by trusting consumers (at $17.95 retail). I invite the lazy editor of this book to check my math.

Summary: Full of mistakes
Review: I am only into Chapter 3 and have found numerous mistakes. Including mistakes in important formulas such as the Quadratic Formula. I do not recommend this book to anyone who already has problems with math!

Summary: Read this book if you want to do poorly in math
Review: I was bothered by the review written by Antonios Giannakas. Mr. Giannakas calls himself a mathematician, I am not convinced he ever read the book. If I (an undergrad.) can find numerous mistakes in this math text, a MATHEMATICIAN should be appalled by the amount of incorrect information in this book. It is hard to believe this book was ever published in the first place. STAY AWAY FROM THIS BOOK!

Summary: publisher not responsive to error information
Review: Like the other reviewers for this book, I found many errors. Fortunately for me, I am reviewing the material rather than learning for the first time. I can't imagine how frustrated and inadequate new learners must feel as they try to identify and apply the rules of math with incorrect answers to both examples and self-test problems. I would recommend new learners look to another book to learn Precalculus. While I have found other Wiley Self Teaching Guides to be accurate and very helpful, Wiley Publishing didn't respond to my suggestion to add a correction paper to every copy of this edition (the minimum ethical response). I would also that any one considering a Wiley Publishing purchase to check with online reviews before purchasing.

Summary: Too many errors to be useful, too few sample problems
Review: The presentation of the subject matter is very adroit, but the problem with the book is two fold: 1) there are numerous errors. For instance, on page 150 problem 1 can only be solved using one measure of the triangle, yet the other measure of the triangle is incorrect for the degree measure provided. In the same set of sample problems, the 7th problem is entirely inconsistent with errors in both the problem statement, the solution statement, and the diagram of the solution statement. This is only a single example, but I marked each problem I found wrong in the book and found that there is a high (~10%) error rate . As another reviewer pointed out, there are even errors in the discussion of identities and axioms, which is horrendous for the students. Errors in problems sets only confuse people, but errors in the lesson is catastrophic, especially in a section you're supposed to memorize. 2) There simply are not enough problem sets to do in order to gain a mastery of the subject matter. There are usually 6 or 7 problems per section, and no additional problems which conclude a chapter. The standard textbook provides this sort of exhaustive problem sets, and this is quite useful for a mastery of the subject. You may be intimately familiar with the assertions of the text, but you will have a hard time applying them without practice.
