Respected for its detailed guidance in using technology, CONTEMPORARY PRECALCULUS: A GRAPHING APPROACH, Fifth Edition, is written from the ground up to be used with graphing technology--particularly graphing calculators. The text has also long been recognized for its careful, thorough explanations and its presentation of mathematics in an informal yet mathematically precise manner. The graphing approach is supported by realistic applications, including many using real data and numerous new ones. Thomas W. Hungerford and new coauthor Douglas J. Shaw also include a greater emphasis than many texts on the "why?" of mathematics--which is addressed in both the exposition and in the exercise sets by focusing on algebraic, graphical, and numerical perspectives.
