I bought this textbook from ecampus and it is cheaper than my school bookstore. This book is very well written. I am using it as my classroom text for the second year with very good results. This textbook is very good and it gives answers for all the questions with a brief explanation . The material isn't difficult (and it's actually enjoyable) if you learn it step by step. This textbook is another representation of mathematicians trying to explain easy material in a simple and interesting way.

Great textbook  March 11, 2011

My daughter has to buy this used textbook for 10th grade glass. She likes it though because it shows how to do the problems. You can actually use it to see how to complete an assignment. That seems like a given, but was not the case with previous texts she had to use. This textbook encourages graphical, numerical, and algebraic modeling of functions as well as a focus on problem solving, conceptual understanding, and facility with technology. I can say this the best book you can buy for Graphical, Numerical, Algebraic concepts and properties.

Precalculus : Graphical, Numerical, Algebraic: 4.5 out of 5 stars based on 2 user reviews.

Summary

In this new edition of Precalculus, Seventh Edition, the authors encourage graphical, numerical, and algebraic modeling of functions as well as a focus on problem solving, conceptual understanding, and facility with technology. They responded to many helpful suggestions provided by students and teachers in order to create a book that is designed for instructors and written for students.

This book covers all of the needed chapters and concepts that are needed for Calculus. While most books show you complicated math expressions and equations to explain a rule, this book both explains it in an easy to understand way, and it shows it in simple and complex expressions and equations.

This textbook also has calculator views for all of the examples; this includes graphs and multi entry calculations. As a result, we believe that the changes made in this edition make this the most effective precalculus text available today.
