Title: Very unclear
Product review: This book is one of the most unclear concepts i have ever tried to learn. The examples are really tough and sadly have nothing to do with the exercises themselves which made my self learning very long, boring, and pretty much a waste of time. I understand the graphing, but i dont understand why they add calculus problems to it like the difference qutient. But on the plus side, the cover and the pages are really nice and good looking. But the examples themselves are long and a waste of paper, no offense. I wouldn't really recomend this book for self teaching, but u can use it maybe if u have a tutor which i dont have. Good luck shopping for a trig book! :P
