II General comments on the purpose of each section and its classroom use, with mathematical and didactic information on teaching practice and pedagogical aspects. Some of the comments refer to whole chapters and are indicated accordingly. Changes in Problem Sets The major changes in this edition of the text are listed and explained in the Preface of the book. They include global improvements produced by updating and streamlining chapters as well as many local improvements aimed at simplification of the whole text.
Speedy orientation is helped by chapter summaries at the end of each chapter, as in the last edition, and by the subdivision of sections into subsections with unnumbered headings. Resulting effects of these changes on the problem sets are as follows. The problems have been changed. Thus, the danger of overemphasizing minor techniques and ideas is avoided as much as possible. These changes in the problem sets will help students in solving problems as well as in gaining a better understanding of practical aspects in the text.
It will also enable instructors to explain ideas and methods in terms of examples supplementing and illustrating theoretical discussions—or even replacing some of them if so desired. This request repeatedly stated in the book applies to all the problem sets. Of course, it is intended to prevent the student from simply producing answers by a CAS instead of trying to understand the underlying mathematics.
Orientation on Computers Comments on computer use are included in the Preface of the book. Software systems are listed in the book at the beginning of Chap.
Some additions on population dynamics appear in Sec. Electric circuits are shifted to Chap. This avoids repetitions that are unnecessary and practically irrelevant. Basic Concepts. Modeling, page 2 Purpose. To give the students a first impression what an ODE is and what we mean by solving it. Background Material. For the whole chapter we need integration formulas and techniques, which the student should review. General Comments This section should be covered relatively rapidly to get quickly to the actual solution methods in the next sections.
Equations 1 — 3 are just examples, not for solution, but the student will see that solutions of 1 and 2 can be found by calculus, and a solution y ex of 3 by inspection. Problem Set 1. Some books use the term to mean a solution that includes all solutions, that is, both the particular and the singular ones. We do not adopt this definition for two reasons. First, it is frequently quite difficult to prove that a formula includes all solutions; hence, this definition of a general solution is rather useless in practice.
Second, linear differential equations satisfying rather general conditions on the coefficients have no singular solutions as mentioned in the text , so that for these equations a general solution as defined does include all solutions. Second order. First order.
