This review book offers high school students in New York State advance preparation for the Regents Exam in Algebra 2/Trigonometry. Fourteen chapters review all exam topics and include practice exercises in each chapter. The book concludes with a sample Regents-style exam presenting problems similar to those that will appear on actual exams. Answers are provided for all questions. Topics covered in this book are: algebraic operations, functions and relations, types of functions, composition and inverses of functions, transformation of functions, imaginary and complex numbers, exponential and logarithmic functions, trigonometric functions, trigonometric graphs, trigonometric identities and equations, applications of trigonometry, probability and statistics, regression, and sequences and series.
My only complaint about the book is the number of errors in the book. In working through the book, I discovered more than a dozen mathematical errors in the example problems and practice problem solutions. I confirmed the errors using my Mathway.com subscription. Even with these errors, the book provides an excellent review source. It could be problematic for someone with weaker skills, though, trying to figure out how to complete certain examples, when the problems in the book are, in fact, wrong. In section 3.7, for example, 3 of the 7 examples worked out have errors in them. Two of them are factored incorrectly, and one of them has a substitution error.
In addition, the book fails to give many detailed illustrative problems before jumping to much harder examples. It is always important, and particularly in a review book, to give the reader numerous examples which are graduated in difficulty throughout the book and for which the solutions are written out in detail.
Also, since these review books are usually used as an addition to a text book so that students can continually strengthen their skills with spiraled exercises, they should also provide a great number of exercises at the end of each section.
This book fails to do either of these.
I would like to amend this review to state that, after working through the book with my student, like the previous reviewers, I had to correct some errors in the book. Nothing major that a teacher well-versed in the topics cannot spot, but it can be very confusing and frustrating for someone trying to work through this book alone. If you want to use this book, I highly recommend a tutor. Overall, it is a good review book, if a bit short on examples. For this reason and also the multiple errors in it, I recommend again to work through this book with someone who knows the topics well.
