This market-leading text continues to provide students and instructors with sound, consistently structured explanations of the mathematical concepts. Designed for a one-term course that prepares students to study calculus, the new Seventh Edition retains the features that have made Trigonometry a complete solution for both students and instructors: interesting applications, cutting-edge design, and innovative technology combined with an abundance of carefully written exercises.
The book was clear enough on most concepts while the first exercises where simple enough and last complex enough.
The only thing bad about the book is that at some points the exercises didn't have enough material behind them to understand them clearly (usually they were the last few exercises) but a quick google search and or youtube video solved that. Also it had quite a few etymological questions that were not that clear.
