Trig Identities Practice Workbook with Answers: 10 (Improve Your Math Fluency)

An excellent workbook for revising and identifying weaknesses in the fundamentals of trigonometry. Clearly laid out subject matter with problems and answers with clearly explained methodology. An exceptional study aide .

Good book

Ce livre indispensable et génial, contient absolument tout ce qui est nécessaire de savoir sur le sujet, y compris les exercices qui permettent le raisonnement, le controle de l'assimilation et l'aide à la mémorisation du processus de solutionnement des problèmes abordés.

I used to hate doing proofs in college math classes. But this book is great! Challenging trig formulas that you can skillfully derive! This book is essential to integration in calculus problems. Loving it!

Good book!

C'est un bon livre d'exercices, c'est très bien pour revoir la trigonométrie

I’m a 68 y/o man, retired, who was never very fluent using trig identities, much to my detriment in integral calculus. I’ve got several trig books and tried self-study multiple times since calculus but nada. Then I saw a review of this book by The Math Sorcerer on YouTube and picked up a copy based on his recommendation combined with the very reasonable cost. I received this book y’day, opened it with curiosity and was immediately captivated. The writing is clear and concise and provides the motivation to understand why a particular subject is important. I’ve studied they Pythagorean Identities many times but just browsing the chapter made “the light come on for me.” I immediately grabbed a sheet of paper and started following his explanation and examples, then immediately started doing chapter exercises. Browsing through the rest of this book I see the light come on for me chapter after chapter. I spent hundreds of hours flailing about in university mathematics, struggling, failing and wasting my time. I would have understood so much more if I had this book when I was a teenager in school. Buy this book! I see the author has many other books available. The geometry proofs book is next!
