Customer Reviews of Precalculus : A Graphing Approach

Disappointed
I was primarily disappointed with the lack of rigor. But it has more pretty pictures than math textbooks I remember from high school, in case you need that sort of thing to keep your (or your students') interest. I would rather have paid less for a black-and-white text that doesn't hurt your arms to hold up to read (the dimensions of the book also make that awkward). There are nice little blurbs about various relevant/famous mathemeticians. The book strives to give a lot of real-world examples, and for that I give it 3 stars instead of 2. If you are looking for a book with that kind of emphasis, you may find this to be just what you want. I have to agree with an earlier reviewer that my highschool trig and precalc course were much more detailed and had more depth.

PS: I am still searching for an errata sheet.

Clear Writing, Great Examples and Problems
I have taught from this text for 3 years now. It is excellent. My students like the text and find the explanations helpful. I would recommend this text to any teacher who is hunting for a good preparation for calculus.

no new material
this book does not cover any new material learned in even a BAD high school trigonometry course and ninth grade algebra other than polar cooridinates and parametric equations. do not use this above the high school level. there is ALOT of stuff you already know. don't use this book even for a review unless you dont know ninth grade math. the topics of functions are so obvious, yet he covers them over about 7 chapters.
