"Approaching Precalculus Mathematics Discretely introduces concepts of discrete mathematics through the computer, making them easier to teach and more fun to learn. Philip Lewis shows how this can be accomplished using the Logo language to apply and explore much of the material in standard high school advanced algebra and precalculus programs. He develops sophisticated programming techniques in conjunction with mathematical concepts that make the book a model for teachers looking for ways to integrate computers into the mathematics curriculum. The opening chapter introduces the use of Logo to express a variety of basic mathematical functions. The next four chapters broaden the discussion to include elementary vector operations, in the plane and linear transformations and matrix operations defined as vector-valid functions. Chapter 4 applies the theory of linear transformations to the mapping of two dimensional geometric objects drawn on the computer screen. Chapter 5 takes up mathematical induction and recursion. This allows the transformation theory of chapter 4 to be extended to wire frame objects in space that are projected on the computer screen. Chapter 7 constructs a graphing utility that is used in subsequent chapters to examine the graphs of a variety of functions and to introduce the concept of a limit. This extends to an intuitive introduction to slope and the derivative in order to establish a territory for the calculus. The two chapters that follow examine the traditional cyclic functions from a graphic and transformational point of view. The book concludes by outlining explorations of topics from earlier chapters. Philip G. Lewis teaches mathematics and computer science atLincoln Sudbury Regional High School in Sudbury Massachusetts. "Approaching Precalculus Mathematics Discretely" is included in the series Exploring with Logo, edited by E. Paul Goldenberg.

The TI-85 is the latest and most powerful graphing calculator produced by Texas Instruments. This book describes the use of the TI-85 in courses in precalculus, calculus, linear algebra, differential equations, business mathematics, probability, statistics and advanced engineering mathematics. The book features in-depth coverage of the calculator's use in specific course areas by distinguished experts in each field.

Popular among university applicants and their advisers alike, these guides presents a wide range of information on a specific degree discipline, laid out in tabular format enabling at-a-glance course comparison.

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.

Building off the success of Zill and Dewar's popular Precalculus with Calculus Previews, Fourth Edition, the new Expanded Volume includes all the outstanding features and learning tools found in the original text while incorporating additional coverage that some courses may require. With a continued aim to keep the text complete, yet concise, the authors added three additional chapters making the text a clear choice for many mainstream courses. New chapters include: Triangle Trigonometry, Systems of Equations and Inequalities, and Sequences and Series. This student-friendly, four-color text offers numerous exercise sets and examples to aid in students' learning and understanding, and graphs and figures throughout serve to better illuminate key concepts. The exercise sets include engaging problems that focus on algebra, graphing, and function theory, the sub-text of so many calculus problems. The authors are careful to use the terminology of calculus in an informal and comprehensible way to facilitate the student's successful transition into future calculus courses.
