Precalculus: Graphical, Numerical, Algebraic, Global Edition

For courses in Precalculus

TheRule of Four: A Balanced Approach

Precalculus:Graphical, Numerical, Algebraicprovides a balanced approach to problem solving and a consistent transitionfrom Precalculus to Calculus. A principal feature of this text is the balanceamong the algebraic, numerical, graphical, and verbal methods of representingproblems: the rule of 4. This approach reinforces the idea that to understand aproblem fully, students need to understand it algebraically as well asgraphically and numerically.

The 10thEdition introducesgraphing technology as an essential tool for mathematical discovery andeffective problem solving. This edition also features a full chapter onStatistics to help students see that statistical analysis is an investigativeprocess.
