very high quality, and, in many cases, to carry out complex symbolic manipulations. A high-speed Internet connection offers an enormous range of further possibilities. The fact that so many students now have these capabilities enables instructors, if they wish, to modify very substantially their presentation of the subject and their expectations of student performance. Not surprisingly, instructors have widely varying opinions as to how a course on differential equations should be…

answers in parts (c) and (d) are known only to the nearest mm. IDENTIFY and SET UP: In each case, estimate the precision of the measurement. EXECUTE: (a) If a meter stick can measure to the nearest millimeter, the error will be about 0.13%. (b) If the chemical balance can measure to the nearest milligram, the error will be about 8.3 × 10−3%. (c) If a handheld stopwatch (as opposed to electric timing devices) can measure to the nearest tenth of a second, the error will be about 2.8 ×…

covers the first six chapters and part of Chapter 7 in the introductory semester. The more specialized and applied topics from Chapters 7 to 11 are then covered at our university in a second semester. The informal, student-oriented style is retained and, if it succeeds, has the flavor of an interactive lecture by the author. Learning Tools Approximately 30 percent of the problem exercises, and some fully worked examples, have been changed or are new. The total number of problem…
