Most math and science study guides are a reflection of the college professors who write them: dry, difficult, and pretentious. The Humongous Book of Trigonometry Problems is the exception. Author Mike Kelley has taken what appears to be a typical trigonometry workbook, chock full of solved problems— more than 750! —and made notes in the margins adding missing steps and simplifying concepts and solutions, so what would be baffling to students is made perfectly clear. No longer will befuddled students wonder where a particular answer came from or have to rely on trial and error to solve problems. And by learning how to interpret and solve problems as they are presented in a standard trigonometry course, students become fully prepared to solve those difficult, obscure problems that were never discussed in class but always seem to find their way onto exams. Review: Great book and series! - Michael Kelley's series is the best. I have used some of his other books (Algebra and Calculus) as tutoring aids. I needed to replace the Calculus and Algebra books, so I bought this one as well.It did not disappoint. Like his other books, Kelley uses LOTS of examples and problems and they all have good explanations. For example, I was tutoring someone last night who was struggling with a Trig problem that required factoring. We talked through how to factor, and when I turned to that section in Kelley's book, there were a few problems that required factoring, and Kelley walked the reader through factoring! Review: Just believe the hype - My child is in 8th grade and it really helped. I also had to sit with my child when I was teaching from this book. I also learned a lot from this book and it refreshed a lot of my concepts. It really gave my child a good confidence. You can't go wrong with this book. I would highly suggest it for 8th and 9th graders. ## Features - Used Book in Good Condition ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #792,376 in Books ( See Top 100 in Books ) #23 in Trigonometry (Books) #1,224 in Study Guides (Books) #2,588 in Education Workbooks (Books) | | Customer Reviews | 4.6 out of 5 stars 237 Reviews | ## Images ![The Humongous Book of Trigonometry Problems: 750 Trigonometry Problems with Comprehensive Solutions for All Major Topics - Image 1](https://m.media-amazon.com/images/I/81+g2jUP8YL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great book and series! *by T***E on January 18, 2018* Michael Kelley's series is the best.
