Welcome to Trigonometry: Seventh Edition. We are pleased to present this new edition of our textbook in which we focus on making the mathematics accessible, supporting student success, and offering instructors flexible teaching options.
Accessible to Students
Over the years we have taken care to write this text with the student in mind. Paying careful attention to the presentation, we use precise mathematical language and a clear writing style to develop an effective learning tool. We believe that every student can learn mathematics, and we are committed to providing a text that makes the mathematics of the trigonometry course accessible to all students. For the Seventh Edition, we have revised and improved many text features designed for this purpose. Throughout the text, we now present solutions to many examples from multiple perspectives—algebraically, graphically, and numerically. The side-by-side format of this pedagogical feature helps students to see that a problem can be solved in more than one way and to see that different methods yield the same result. The side-by-side format also addresses many different learning styles. We have found that many trigonometry students grasp mathematical concepts more easily when they work with them in the context of real-life situations. Students have numerous opportunities to do this throughout the Seventh Edition. The new Make a Decision feature has been added to the text in order to further connect real-life data and applications and motivate students. They also offer students the opportunity to generate and analyze mathematical models from large data sets. To reinforce the concept of functions, each function is introduced at the first point of use in the text with a definition and description of basic characteristics. Also, all elementary functions are presented in a summary on the endpapers of the text for convenient reference. We have carefully written and designed each page to make the book more readable and accessible to students. For example, to avoid unnecessary page turning and disruptions to students’ thought processes, each example and corresponding solution begins and ends on the same page.
