Book Preface
It has been over twenty years since we published the first edition of this book. Over that period, our original contention that numerical methods and computers would figure more prominently in the engineering curriculum—particularly in the early parts—has been dra- matically borne out. Many universities now offer freshman, sophomore, and junior courses in both introductory computing and numerical methods. In addition, many of our colleagues are integrating computer-oriented problems into other courses at all levels of the curriculum. Thus, this new edition is still founded on the basic premise that student engineers should be provided with a strong and early introduction to numerical methods. Consequently, although we have expanded our coverage in the new edition, we have tried to maintain many of the features that made the first edition accessible to both lower- and upper-level undergraduates. These include:
Problem Orientation. Engineering students learn best when they are motivated by problems. This is particularly true for mathematics and computing. Consequently, we have approached numerical methods from a problem-solving perspective.
Student-Oriented Pedagogy. We have developed a number of features to make this book as student-friendly as possible. These include the overall organization, the use of introductions and epilogues to consolidate major topics and the extensive use of worked examples and case studies from all areas of engineering. We have also en- deavored to keep our explanations straightforward and oriented practically.
Computational Tools. We empower our students by helping them utilize the standard “point-and-shoot” numerical problem-solving capabilities of packages like Excel, MATLAB, and Mathcad software. However, students are also shown how to develop simple, well-structured programs to extend the base capabilities of those environments. This knowledge carries over to standard programming languages such as Visual Basic, Fortran 90, and C/C + +. We believe that the current flight from computer programming represents something of a “dumbing down” of the engineering curriculum. The bottom line is that as long as engineers are not content to be tool limited, they will have to write code. Only now they may be called “macros” or “M-files.” This book is designed to empower them to do that.
Beyond these five original principles, the seventh edition has new and expanded problem sets. Most of the problems have been modified so that they yield different numerical solu tions from previous editions. In addition, a variety of new problems have been included.
The seventh edition also includes McGraw-Hill’s Connect® Engineering. This online
homework management tool allows assignment of algorithmic problems for homework, quizzes, and tests. It connects students with the tools and resources they’ll need to achieve success. To learn more, visit www.mcgrawhillconnect.com.McGraw-Hill LearnSmart™ is also available as an integrated feature of McGraw-Hill Connect® Engineering. It is an adaptive learning system designed to help students learn faster, study more efficiently, and retain more knowledge for greater success. LearnSmart assesses a student’s knowledge of course content through a series of adaptive questions. It pinpoints concepts the student does not understand and maps out a personalized study plan for success. Visit the following site for a demonstration. www.mhlearnsmart.com
As always, our primary intent in writing this book is to provide students with a sound introduction to numerical methods. We believe that motivated students who enjoy numerical methods, computers, and mathematics will, in the end, make better engineers. If our book fosters an enthusiasm for these subjects, we will consider our efforts a success.
Acknowledgments. We would like to thank our friends at McGraw-Hill. In particular, Lorraine Buczek and Bill Stenquist, who provided a positive and supportive atmosphere for creating this edition. As usual, Beatrice Sussman did a masterful job of copyediting the man- uscript and Arpana Kumari of Aptara also did an outstanding job in the book’s final production phase. As in past editions, David Clough (University of Colorado), Mike Gustafson (Duke), and Jerry Stedinger (Cornell University) generously shared their insights and suggestions. Use- ful suggestions were also made by Bill Philpot (Cornell University), Jim Guilkey (University of Utah), Dong-Il Seo (Chungnam National University, Korea), Niall Broekhuizen (NIWA, New Zealand), and Raymundo Cordero and Karim Muci (ITESM, Mexico).
