## Description

Trig Identities Practice Workbook with Answers (Improve Your Math Fluency) [McMullen, Chris] on desertcart.com. *FREE* shipping on qualifying offers. Trig Identities Practice Workbook with Answers (Improve Your Math Fluency)

Review: Necessary for substitution methods in integral calculus - 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!
Review: If you are going to study or are studying trigonometry, absolutely buy this book. - 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!

### ⭐⭐⭐⭐⭐ Practice, practice, practice
*by R***E on July 1, 2024*

Trig, like all other branches of mathematics is learned by repeated practice, and the series of instructive books by Chris McMullen make you learn throught repetition. I have found that even students who are very good at calculus have large gaps in their trig knowledge, and this is a excellent resource to plug those gaps. This is probably because trig is typically introduced on a 'need to know' basis, and must students do not have a thorough formal trig background.
