Whats New in the Second Edition of Precalculus with Trigonometry?
The second edition has integrated some new topics, improved the presentation of sections identified by survey respondents, and added new features that emphasize the development of student reading skills and the effective use of technology for visualizing mathematics. Specific changes include: • A new Reading Analysis feature at the start of most problem sets helps students develop their ability to read for understanding of mathematical content. • Java-based Dynamic Precalculus Explorations referenced in the text are provided at the Keymath.com website for students to investigate concepts in a dynamic geometry environment. • The presentation of composition of functions and function inverses has been improved by placing a greater emphasis on numerical and graphical representations (Chapter 1). • A new section on rotary motion provides a real world context for the use of radians (Chapter 3). • The presentation of logarithms has been improved to help students better understand that logarit
