About the Author

Marge Lial has always been interested in math; it was her favorite subject in the first grade! Marge's intense desire to educate both her students and herself has inspired the writing of numerous best-selling textbooks. Marge, who received Bachelor's and Master's degrees from California State University at Sacramento, is now affiliated with American River College. Marge is an avid reader and traveler. Her travel experiences often find their way into her books as applications, exercise sets, and feature sets. She is particularly interested in archeology. Trips to various digs and ruin sites have produced some fascinating problems for her textbooks involving such topics as the building of Mayan pyramids and the acoustics of ancient ball courts in the Yucatan.

When John Hornsby enrolled as an undergraduate at Louisiana State University, he was uncertain whether he wanted to study mathematics education or journalism. His ultimate decision was to become a teacher, but after twenty-five years of teaching at the high school and university levels and fifteen years of writing mathematics textbooks, both of his goals have been realized. His love for both teaching and for mathematics is evident in his passion for working with students and fellow teachers as well. His specific professional interests are recreational mathematics, mathematics history, and incorporating graphing calculators into the curriculum. John's personal life is busy as he devotes time to his family (wife Gwen, and sons Chris, Jack, and Josh). He has been a rabid baseball fan all of his life. John's other hobbies include numismatics (the study of coins) and record collecting. He loves the music of the 1960s and has an extensive collection of the recorded works of Frankie Valli and the Four Seasons.

1.0 out of 5 stars Terrible, difficult to understand book will make you hate math, February 25, 2009

This review is from: Trigonometry (9th Edition) (Hardcover)

Here's a list of why this book sucks
1) explanation of concepts are very difficult to understand
2) Worked out examples are not clearly explained
3) will require further tutoring

The worse thing about this book is that after you finish, you still wont have a solid grasp of basic concepts of Trig

This review is from: Trigonometry (9th Edition) (Hardcover)

This book is terrible. I'm sure there are plenty of other books that go deeper in depth of the subject than this one. I have never had any sort of reason to write a review on a book until I had to endure a semester of this tripe. In the examples, they don't explain the problems well and then they include problems that need much more explaining than what they gave in the first place. Every tutor I encountered thought the book was bad and it made my fellow students frustrated as well. Unfortunately, if the school uses this book, you have to go along with it. I was forced to waste my money on it. Bad bad bad.

1.0 out of 5 stars I used to liked math, once upon a time..., February 25, 2011

This review is from: Trigonometry (9th Edition) (Hardcover)

This book is not a good textbook at all. My college required it, and since my instructor is not so clear, I have no other form of learning from this material. The explanations of concepts are weak, as well as the applications of formulas to problems. At first I was pleased to see such a (physically) light weight math book, only to realize that with less weight comes a price of vague instruction. I am still in awe of the fact that this textbook was chosen by the math department at my college. It really reminds you that if someone already understands the material, they can hardly relate to those who don't. That is what this book seems to be; a text written from the perspective of people who are knowledge in the subject, to people who somewhat already comprehend trigonometry.

If you have a math mentality, then this book may work, but for me (who did very well in algebra with a great book "College Algebra with Modeling and Visualization (4th Edition)") this book is not even slightly satisfactory.
