All in all a good teaching tool, but I would tend to give more praise to the first half than the more challenging second half, I.e.- the trigonometry chapters and later. The material, I'm assuming, is pretty much the same as any other textbook on the subject, yet more attention is paid to giving a wider array of examples on the "easier" material. I understand that as you progress in the world of mathematics, the concepts/vocabulary become familiar, but this is a deceptive familiarity owing it's existence to the enveloping nature of just studying this universal language; the same attention to explanation should be given on all fronts. Anyway, this book is most useful when paired with it's solutions manual, where applications are shown conceptually alongside their answers and a bit more attention is given to explaining the more challenging topics.
