توضیحات: | The goal of this book is the same as the goal of the original edition, namely, to present a one-semester, brief treatment of the key ideas, models, and so-lution methods in elementary diﬀerential equations. As in the ﬁrst edition, there remains an intimate connection between the mathematics and applica-tions. There are many excellent texts on diﬀerential equations designed for the standard sophomore course, but, in spite of the fact that most courses are one semester in length, they have evolved into calculus-like presentations that in-clude a large collection of methods and applications, packaged with student manuals, and Web-based notes, projects, and supplements. All of this comes in several hundred pages of text with busy formats. Many students do not have the time or desire to read voluminous texts and explore Internet supplements. Therefore, the format of this text is diﬀerent; it is more concise. I have tried to write to the point with plain language. Many worked examples and exercises are included. A student who works through this primer will have the tools to go to the next level in applying diﬀerential equations to more diﬃcult problems in engineering, science, and applied mathematics. It gives some instructors who want more concise coverage an alternative to existing texts. | تعداد بازدید: 273 دریافت فایل |
