Algebra and Trigonometry 3rd Edition, by James Stewart, Lothar Redlin and Saleem Watson explains concepts simply and clearly, without glossing over difficult points. Problem solving and mathematical modeling are introduced early and reinforced throughout, providing students with a solid foundation in the principles of mathematical thinking.
Comprehensive and evenly paced, the book provides complete coverage of the function concept, and integrates a significant amount of graphing calculator material to help students develop insight into mathematical ideas. The authors' attention to detail and clarity, the same as found in James Stewart's market-leading Calculus book, is what makes this book the market leader.
Approximately 20% of the exercises in the text are new. In addition, each exercise set has been restructured to begin with new concept exercises, and reorganized to more closely follow the exposition in the corresponding section. The section entitled "Principles of Problem Solving" is now a Prologue to the book. Problem Solving sections, each highlighting a particular problem solving principle, are now posted on the Book Companion Website.
Discovery Projects, which encourage and motivate students to further explore chapter topics, are now available on the Book Companion Website. All examples in the book are now paired with a new Now Try Exercise XX, allowing students to reinforce their understanding of a concept by practicing the technique that is involved. This integration also teaches and encourages students to solve rather than just memorize.
Chapter 3 has been completely rewritten to focus more sharply on the fundamental and crucial concept of function. The material on quadratic functions, formerly in this chapter, is now part of the chapter on polynomial functions. Chapter 4 now begins with a section on quadratic functions, leading to higher degree polynomial functions.
Chapter 6 includes a new section on inverse trigonometric functions and right triangles (Section 6.4), which is needed in applying the Laws of Sines and Cosines in the following section, as well as for solving trigonometric equations in Chapter 8. Chapter 7 includes a new section on inverse trigonometric functions (Section 7.5) to better segue into the section on harmonic motion that follows. Chapter 8 has been completely revised, including two new sections on trigonometric equations (Sections 8.4 and 8.5) that expand coverage of this topic.
