Not a bad book, but definitely wouldn't be good for self studying.

My school uses Larson books all the way from elementary algebra, up through Calculus. This Trigonometry book isn't bad, but it does lack well structured explanations in many areas. There are a lot of topics that show an example of one type of problem, but they don't really show how to manipulate the same concept into a different scenario. Some of the trig identities like double angle formulas, sum-to-product, and product-to-sum formulas are barely explained. They give one basic example of how to use the formula, and they don't elaborate on how to use it in a more complicated problem.
One very strong point that this book has, along with the other Larson books, is a very wide variety of practice exercises. The end of chapter sections begin with simpler exercises, and progress up through the different concepts in a given section very logically. Each section of practice exercises has a good variety of word problems, many of which will apply all of the concepts you've learned in a given section, as well as forcing you to recall material from previous sections.
I also really like the "proofs in mathematics" sections at the end of each chapter, because they go more in depth about why a certain formula works. This books includes proofs of most of the common trig identities, which is very useful. I'm the type of person that understands an idea better when I can actually see WHY something works, and WHY we're doing it that way, rather than just having to rote memorize a certain formula. Seeing these proofs helps a lot with that.
I also bought the accompanying student solutions manual. I'm writing a separate review for that, but I'll touch on it briefly here as well. The student solutions manual is incredibly hit or miss. Some of the problems are worked out completely, and other problems basically just show the original problem statement, followed by one intermediate step, then the final answer. Really? It might help to see a few of the steps in between, and see an explanation as to how we got from point A to point B.
Overall, this is a solid Trig book, but I don't think I'd recommend it for self studying.
