## Description

**Trigonometry, Tenth Edition**, by Lial, Hornsby, Schneider, and Daniels, engages and supports students in the learning process by developing both the conceptual understanding and the analytical skills necessary for success in mathematics. With the **Tenth Edition**, the authors recognize that students are learning in new ways, and that the classroom is evolving. The Lial team is now offering a new suite of resources to support today’s instructors and students.

New co-author Callie Daniels has experience in all classroom types including traditional, hybrid and online courses, which has driven the new MyMathLab features. For example,

**MyNotes**provide structure for student note-taking, and

**Interactive Chapter Summaries**allow students to quiz themselves in interactive examples on key vocabulary, symbols and concepts. Daniels’ experience, coupled with the long-time successful approach of the Lial series, has helped to more tightly integrate the text with online learning than ever before.
