Xi TO THE STUDENT Authors of books live with the hope that someone actually reads them. Contrary to what you might believe, almost everything in a typical college-level mathematics text is written for you and not the instructor. True, the topics covered in the text are cho- sen to appeal to instructors because they make the decision on whether to use it in their classes, but everything written in it is aimed directly at you the student. So I want to encourage you—no, actually I want to tell you—to read this textbook!

But do not read this text like you would a novel; you should not read it fast and you should not skip anything. Think of it as a workbook. By this I mean that mathemat- ics should always be read with pencil and paper at the ready because, most likely, you will have to work your way through the examples and the discussion. Read—oops, work—all the examples in a section before attempting any of the exercises; the ex- amples are constructed to illustrate what I consider the most important aspects of the section, and therefore, reflect the procedures necessary to work most of the problems in the exercise sets. I tell my students when reading an example, cover up the solu- tion; try working it first, compare your work against the solution given, and then resolve any differences.

I have tried to include most of the important steps in each example, but if something is not clear you should always try—and here is where the pencil and paper come in again—to fill in the details or missing steps. This may not be easy, but that is part of the learning process. The accumulation of facts fol- lowed by the slow assimilation of understanding simply cannot be achieved without a struggle. Specifically for you, a Student Resource and Solutions Manual ( SRSM) is avail- able as an optional supplement. In addition to containing solutions of selected prob- lems from the exercises sets, the SRSM has hints for solving problems, extra exam- ples, and a review of those areas of algebra and calculus that I feel are particularly important to the successful study of differential equations. Bear in mind you do not have to purchase the SRSM; by following my pointers given at the beginning of most sections, you can review the appropriate mathematics from your old precalculus or calculus texts.

In conclusion, I wish you good luck and success. I hope you enjoy the text and the course you are about to embark on—as an undergraduate math major it was one of my favorites because I liked mathematics that connected with the physical world. If you have any comments, or if you find any errors as you read/work your way through the text, or if you come up with a good idea for improving either it or the SRSM, please feel free to either contact me or my editor at Brooks/Cole Publishing Company: [email protected] TO THE INSTRUCTOR WHAT IS NEW IN THIS EDITION? First, let me say what has not changed. The chapter lineup by topics, the number and order of sections within a chapter, and the basic underlying philosophy remain the same as in the previous editions. In case you are examining this text for the first time, Differential Equations with Boundary-Value Problems, 7th Edition, can be used for either a one-semester course in ordinary differential equations, or a two-semester course covering ordinary and partial differential equations.

The shorter version of the text, A First Course in Differential Equations with Modeling Applications, 9th Edition, ends with Chapter 9. For a one-semester course, I assume that the students have successfully completed at least two-semesters of calculus. Since you are reading this, undoubt- edly you have already examined the table of contents for the topics that are covered. You will not find a “suggested syllabus” in this preface; I will not pretend to be so wise as to tell other teachers what to teach. I feel that there is plenty of material here to pick from and to form a course to your liking. The text strikes a reasonable bal- ance between the analytical, qualitative, and quantitative approaches to the study of differential equations. As far as my “underlying philosophy” it is this: An under- graduate text should be written with the student’s understanding kept firmly in mind, which means to me that the material should be presented in a straightforward, readable, and helpful manner, while keeping the level of theory consistent with the notion of a “first course.” For those who are familiar with the previous editions, I would like to mention a few of the improvements made in this edition.
