The Humongous Book of Trigonometry Problems

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!

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.

very big for $10

I liked the detailed explanations. It seems to have been well proofread but I have found an error on page 123 , in the first line of text which says To calculate sin theta ( and its reciprocal sec theta ). This is wrong. The reciprocal of sin is the cosecant.

I used this book, along with others from the same author, to review math work I did in high school and college. It covers everything a high school trigonometry course could conceivably include, but builds up very gradually, so you don't get lost. I highly recommend it. For the price, it is a steal!

I HAVE FOUND THE BOOK VERY WELL DONE AS WELL AS ENJOYABLE AND EDUCATIONAL. I AM USING IT AS A RECREATIONAL REVIEW AND A CHALLENGE IN MY OLD AGE. AS A RETIRED MATH TEACHER WITH 38 YEARS ON THE JOB FROM 2O YEARS AGO, I WOULD RECOMMEND THE BOOK TO A MOTIVATED STUDENT WHO WAS WILLING TO PUT THE TIME IN TO SUCCEED. CONGRATULATIONS TO MR KELLEY ON A FINE EFFORT TO HELP STUDENTS WHO ARE LOOKING TO HELP THEMSELVES. I ANTICIPATE DOING THE REST OF THE SERIES. MY GOAL: EVERY PAGE, EVERY PROBLEM, A HUMONGOUS TASK!

I had never been moved to laugh out loud by a math book until reading this one. Kelley provides crystal clear explanations laced with a dry wit that actually makes the highly repetitive practice needed to master trig almost enjoyable. This is not your typical math textbook where even after reading through a chapter you might be just as lost as when you started because it assumes too much prior knowledge. At the same time, nothing in this book feels so dumbed down as to be patronizing. I highly recommend it for both trig beginners as well as people brushing up on old trig concepts to make calculus classes easier.

This was a great review of how trigonometry works. I especially like that the text clearly spells every single step out in notes in the margins - if you get it you can skim through, but if you are confused you can read more for a far more in-depth explanation. In addition, I appreciated that the book includes sections on polar coordinates, which often get overlooked.

I have several books on trigonometry and I have come to a roadblock with each of them because the authors throw you unexpected curve balls or introduce subjects without explanations. This book uses technical terms and formulas but thoroughly explains each concept . I have not read the whole book but am working my way through it. So far I am pleasantly surprised at how much I am able to absorb and enjoy. I would recommend this book and it's author wholeheartedly. Jim

Ótimo pra treinar o inglês e relembrar a matemática através dos muitos exercícios resolvidos passo a passo.

I am completely satisfied with my purchase.

This book is part of a series by mathematics teacher Michael Kelly which covers most of the high school mathematics curriculum. Like his other books, this book contains a large set of problems in 18 chapters covering the standard elements of a trigonometry course. The main strength of this book are the problems. The student is encouraged to work through the problems on their own, while Kelly provides worked out solutions in a lot of detail. This book does not replace mathematics textbooks which supply the relevant theory, but as every mathematics teacher knows, the only way to learn mathematics is to do the problems. This book is an excellent resource for students who are doing trigonometry in their school classes, as well as for college students or adults who are preparing for more advanced mathematics courses in calculus or linear algebra, which require a sound knowledge of basic math, algebra, geometry and trigonometry.

Its great for students and anyone who has forgot a few things.
