Ron Larson, David E. Heyd, Robert P. Hostetler - Trigonometry

This text introduces trigonometry first with a unit circle approach and then with the right triangle. As the best-selling text in the field, Trigonometry provides unparalleled exercises, motivating real-life applications, a supportive pedagogical design, and innovative ancillaries and resources, making it a complete solution for both students and instructors.

• Model It real-life applications in nearly every text section are multi-part exercises that require students to generate and analyze mathematical models. First referenced in the Why You Should Learn It at the beginning of each section, these interesting applications illustrate why it is important to learn the concepts in each section.
• Proofs in Mathematics shows the proofs of selected theorems and demonstrates different proof techniques. For added convenience, in the Sixth Edition these proofs have been moved from an appendix to the end of relevant chapters.
• P.S. Problem Solving, at the conclusion o
