Bert Waits – författare

For use in a graphing required precalculus course, this nationally recognized author team has created a text with the perfect balance of graphical and algebraic representation. With examples and exercises for all levels of students, a focus on the twelve basic functions, and a new section on Data Analysis and Statistical Inference, this is the most current and effective precalculus text on the market today.

For courses in Precalculus

The Rule of Four: A Balanced Approach

Precalculus: Graphical, Numerical, Algebraic provides a balanced approach to problem solving and a consistent transition from Precalculus to Calculus. A principal feature of this text is the balance among the algebraic, numerical, graphical, and verbal methods of representing problems: the rule of 4. This approach reinforces the idea that to understand a problem fully, students need to understand it algebraically as well as graphically and numerically.

The 10th Edition introduces graphing technology as an essential tool for mathematical discovery and effective problem solving. This edition also features a full chapter on Statistics to help students see that statistical analysis is an investigative process.
