Featuring updated content, vivid applications, and integrated coverage of graphing utilities, the ninth edition of this hands-on trigonometry text guides readers step by step, from the right triangle to the unit-circle definitions of the trigonometric functions. Examples with matched problems illustrate almost every concept and encourage readers to be actively involved in the learning process. Key pedagogical elements, such as annotated examples, think boxes, caution warnings, and reviews, help readers comprehend and retain the material.
While the content is merely adequate, what really separates this text from its peers, is the removable tri-fold card of key identities and other trig necessities. Unfortunately a significant part of this card is given over to, effectively, advertising. That space could have been used for more on inverses, etc.
The seventh edition of Analytic Trigonometry with Applications is a textbook. It covers Trigonometry and may be useful to the autodidact or directed learner. I didn't spot any errors, but I didn't put on my editor's hat. Triangles are far more useful than their humble shape suggests. Trigonometry is useful in almost all aspects of science and engineering. Trigonometric functions, such as sine and cosine, define periodic phenomena and circular motion, which are fundamental to understanding how much of the physical world works. Furthermore, due to its roots in astronomy and navigation, trigonometry can be used to measure distances. I am hard-pressed to think of a more useful basic tool.
The book contains practice problems with answers for the odd-numbered problems. The preface declares the use of a graphing calculator or utility unnecessary for using the textbook. If you have an old-school teacher, that is true. The triangles can be set up to use whole numbers, but that is inherent to trigonometry itself.
I enjoyed the book. Thanks for reading my review, and see you next time.
Well, this isn't a book for everyone, but for me it helped to satisfy my goal of trying to keep my mind as sharp as possible for someone in his mid-60's. I actually enjoy math and problem solving. Trigonometry is a subject that has interested me ever since I first learned about it in the early 1970's. It was also something that I was required to know and use in my career.
This book is very good at explaining the many concepts and principles while giving lots and lots of examples with detailed explanations. Of course there are also tons of problems for practicing at the end of each section. All the odd-numbered problems have the answers given in an appendix at the end of the book.
