Bridging Traditional and Reform
|
|
Within a framework of fairly traditional topics, the books incorporate important features of the various calculus reform projects,
Reform Elements:
- Thorough integration of graphing, spreadsheet, and on-line technologies.
- Focus on applications using real data
- Emphasis on
mathematical concepts through the extensive use of conceptual exercises
and pedagogical techniques such as the Rule of Four (numerical,
geometric, algebraic, and communication-oriented approaches to
concepts).
- Through our Internet site, we now add a Fifth element:
interactive discourse. The student can now go on-line and take a
quiz, interact with on-line tutorials, play a zero-sum game with the computer, or watch a visual simulation of a Markov process or a limit. The possibilities are
endless, and the site continues to grow and evolve.
Traditional Elements:
- Inclusion of almost all the topics found in more traditional texts.
- While the books are technology-oriented, the organization of the matertial has been planned to ensure that students equipped with
nothing more than a scientific calculator will not find themselves at a
significant disadvantage.
- The texts are carefully structured and tightly organized for easy navigation and reference, and we have taken pains to be mathematically precise in all our definitions and statements of results.
- Abundance of practice and drill exercises
- Large numbers of application exercises to choose from

Options in Technology
|
|
The use of graphing calculators and computer software has been thoroughly integrated throughout the discussion, examples, and exercise sets, beginning with the first example of the graph of an equation in Chapter 1.
- Flexibility in Choice of Technology
We incorporate all of the following technologies: graphing calculator (based on the TI-83/84), computer spreadhseet (based on Excel), and on-line utilities offered at this web site. As a result, the text can be used in a classroom devoted to a single technology mode (for instance, graphing calculators only) or in a setting where instructors and students can choose different technologies for different topics.
- End-of-Chapter Technology Guides
Each Chapter ends with detailed Technology Guides for the TI-83/84 and Excel that walk the student step-by-step through all the technology-based examples discussed in the chapter.
- Influence of Technology on Material
The focus on technology plays an important conceptual and pedagogical role in our presentation of many topics. For example, our discussion of the operations of arithmetic in Appendix A includes a careful discussion of formula syntax for technology. Our discussion of mathematics of finance includes descriptions of using technology to solve problems normally requiring techniques not norally covered in finite mathematics courses. Our treatment of curve sketching was written with the graphing calculator option in mind, and we have used a flexible approach that can be adapted to the increasingly popular practice of using graphing calculators to draw the graphs and then using calculus to explain the results. (On the other hand, instructors who prefer "by-hand" sketching can simply ignore technology and use the text in a more traditional manner.) Some of the real power of technology is seen in the chapter on applications of the integral, where we guide the student in the use of technology to analyze mathematical models based on real data, make projections, and calculate and graph moving averages.

Exercise Sets
|
|
We regard the strength of our exercise sets as one of the best features of the First Edition. Our comprehensive collection of exercises provides a wealth of material that can be used to challenge students at almost every level of preparation, and includes everything from straightforward drill exercises to interesting and rather challenging applications. We have therefore included, in virtually every section of every chapter:
- Applications Based on Real Data
A most striking distinguishing feature of these texts is the diversity, breadth and sheer abundance of examples and exercises based on real, referenced data from business, economics, the life sciences and the social sciences.. This focus on real data has contributed to the creation of a book that students in diverse fields can relate to, and that instructors can use to demonstrate the importance and relevance of calculus in the real world.
- Communication and Reasoning Exercises
These are exercises designed to broaden the student's grasp of the mathematical concepts, and include exercises in which the student is asked to provide his or her own examples to illustrate a point, design an application with a given solution, "fill in the blank" type exercises, and exercises that invite discussion and debate. These are often exercises with no single correct answer.
- Technology Exercises
Our technology exercises have been designed for all three types of technology discussed in the books: graphing calculator, Excel, and web site technology tools, often in relation to real, referenced data where by-hand computation would be difficult.
- Revisited Themes
Many of the scenarios used in application examples and exercises will be revisited several times throughout the book. Thus, for instance, students will find themselves using a variety of techniques, from graphing through the use of derivatives to elasticity of demand, to maximize revenue in the same application.
- New to 4e: Graduated Difficulty Level and Exercise Hints
We have marked exercises that test basic skills or closely follow examples in the text with green dots. Exercises that are slightly more challenging or not based wholly on examples and sometimes require a student to think "outside the ox" are unmarked. Many sections also include exercises that are more challenging, marked with black diamonds. (Click on the graphic to the right to see examples of all three types of exercise.) Hints are often included that relate exercises to specific examples.
- New to 4e: Expanded Chapter Review Exercise Sets
The chapter review exercise sets have been expanded with the addition of many mnore basic skills exercises and applications. All the applications in the chapter review exercises revolve around the various bueiness and other exploits of fictitious online seller, OHaganBooks.com and CEO John O'Hagan. The diligent reader will be able to track the college career of John O'Hagan's son Billy-Sean and also speculate about his often dubious business decicions.
- Humor
Scattered throughout the exercise sets you can find some that are a touch absurd and, we hope, will elicit a chuckle or two.

Up-To-Date Pedagogy
|
|
We would like students to read this book. We would like students to enjoy reading this book. Thus, we have written the book in a conversational and student-oriented style to encourage the development of the student's mathematical curiosity and intuition. Some unique features of our pedagogy include:
- Question-and-Answer Dialogue
We frequently use informal question-and-answer dialogues that anticipate the kind of questions that may occur to the student and also guide the student through the development of new concepts.
- Quick Examples
Most definition boxes include one or more straightforward examples that a student can use to solidify each new concept as soon as it is encountered.
- FAQs
These are collections of "frequently asked questions" and answers at the end of many sections whose purpose it is to answer common student questions and reinforce new concepts (Click on picture opposite to see a sample.)
- Before We Go On
Most examples are followed by supplementary interpretive discussions under the heading "Before we go on." These discussions may include a check on the answer, a discussion of the feasibility and significance of a solution, or an in-depth look at what the solution means.
- Communication and Reasoning Exercises
These are exercises designed to broaden the student's grasp of the mathematical concepts. They include exercises in which the student is asked to provide his or her own examples to illustrate a point or design an application with a given solution. They also include "fill in the blank" type exercises and exercises that invite discussion and debate. These exercises often have no single correct answer.
- Unique Pedagogical Devices
As instructors, we have all seen students encounter conceptual barriers in finite mathematics and calculus classes. We list a few we are sure you have encountered, and outline how we deal with them:
- Word Problems: Students unable to translate stements into mathematical equaitons
In the chapters on systems of linear equations and linear programming, we carefully coach the student to reword each statement in a specified way that translates easily into symbols
- Differentiation Tequniques: Students unable to decide which rule to use where
In the chapter on techniques of differentiation we describe a "thought experiment" to lead the student to a valid hierarchy of derivatives rules.
- Counting arguments: Students unsure of how to organize information
In the chapter on sets and counting we discuss "decision algorithms:" the student is urged to pretend he or she was going through all the steps in constructing, say, a poker hand of a specified type. The resulting sequence of decisions is then translated into a counting algorithm quite mechanically.
- Matrix Row Operations: Students going around in circles getting nowhere in reducing a matrix
Our dicussion of setting up row operations describes a detailed, step-by-step procedure for students to follow in setting up the appropriate row operations and ways to check the status of the computation.

Application Projects
|
|
Every chapter begins with the statement of an interesting problem scenario that is returned to at the end of that chapter in a section titled "You're the Expert." This extended application uses and illustrates the central ideas of the chapter, and can be used as a reading project, group project, or take-home test. The themes of these applications are varied, and they are designed to be as non-intimidating as possible. Thus, for example, the authors avoid pulling complicated formulas out of thin air, but focus instead on the development of mathematical models appropriate to the topics.
Among the more notable of these applications are an example of modeling Internet spending based on actual data, an example using marginal analysis to design a strategy for regulating sulfur emissions, and an example on using Benford's Law to spot fraudulent tax returns. These applications are ideal for assignment as individual or group projects, and it is to this end that we have included groups of exercises at the end of each.
