A good text on ordinary differential equations with good examples, December 7, 2007
This review is from: A First Course in Differential Equations: The Classic Fifth Edition (Hardcover)
This particular textbook concerns ordinary differential equations. There are plenty of examples, and they are worked in steps that should make the solution strategy clear to any student with at least two previous semesters of calculus. One of the unusual features of the book are essays written by mathematicians present at the end of chapters 3, 4, 5, and 9. Each essay concerns applications of concepts learned in the previous chapter. The book is well illustrated, and motivations for study are included by making the examples solve practical problems such as the charge on a capacitor, solving orthogonal trajectories of the family of a rectangular hyperbola, or even determining the half-life of a radioactive substance. This makes it ideal for engineering students. There are numerous exercises at the end of each chapter and the solutions to odd numbered problems can be found in the back of the book. The following is the table of contents:

Best Book Out There For ODEs, January 29, 2012
This review is from: A First Course in Differential Equations: The Classic Fifth Edition (Hardcover)
This is the best book I've come across for ordinary differential equations, and I've gone through many of them as a mathematics major! Not only did this book teach me the entire subject matter, I continue to go back to it years later whenever I need to review a technique. The explanations are lucid and clear, and the examples provided are very helpful. Most importantly, when presenting a technique, the authors break it down into all possible cases, so that you are ready to handle any type of problem assigned for hw or tests. I highly recommend this book!

Beware of the "Example" Problems, October 4, 2006
This review is from: A First Course in Differential Equations: The Classic Fifth Edition (Hardcover)
Overall, the textbook is decent. However, when it comes to reading the example problems in the text, one can, and probably will, become very confused. In my opinion, the purpose of an example problem in the text is to completely break down all the steps towards finding the solution to the problem for the reader, especially one that is a first-timer in DE. This book fails to do so. As a first-timer in DE, I became more confused reading the example problems than I was when perusing the text. The explanations were neither lucid nor thorough enough for my liking. But do not be discouraged first-timers! It is possible to earn your A using this textbook. With the right amount of motivation and study sessions, your A will come. If I could get an A in this class as a college freshman, then anyone could.
