Product Description
A First Course in Differential Equations with Modeling Applications, 9th Edition strikes a balance between the analytical, qualitative, and quantitative approaches to the study of differential equations. This proven and accessible text speaks to beginning engineering and math students through a wealth of pedagogical aids, including an abundance of examples, explanations, "Remarks" boxes, definitions, and group projects. Using a straightforward, readable, and helpful style, this book provides a thorough treatment of boundary-value problems and partial differential equations.

1 out of 5 starsI now regret taking the class because of this book., 2010-08-29
This book only gives answers to 'selected' odd-numbered problems making it hard to check your work and make sure you know what you are doing. The solutions manual only works out about every third problem. Even then, they are not worked out well. Once again making it hard to check your work. I really regret buying this now.

1 out of 5 starsNot the best book to learn from, 2010-04-02
This book really sucks, it may be concise and clear but it hardly shows examples. Most of the examples are cut off and instead of showing you how they derive the solution they just give it to you written in words. NOT THE BEST BOOK TO LEARN FROM

5 out of 5 starsCost effective!, 2010-02-26
The book for my Diffeq class was $150 in the school store. This is the exact same thing (with a different font and colors) for about $145 less. Every college student should know how to book-hunt like this. Came in great condition and has everything I need for class.

3 out of 5 starsToo expensive with respect to size, 2009-07-16
I just wanted to mention that the ninth edition of this book has only about 400 pages (if you count the index, appendices as well) and that Amazon should update the information of this "new" edition. This fact makes the price of $140 (and it is usually cheaper on Amazon.com than elsewhere) even more insolent.

3 out of 5 starsIt either helps or it doesn't, 2009-07-03
When you look at the solutions, the explanations/processes are very limited. Its like having a math teacher who starts to perform steps in his or her head and then you're left there trying to figure out what the teacher did. Some of the odds are not even that: sometimes, it would only give you a hint.

Most of the odd problems are worked out-as described above; however, sometimes it selectively omits odd problems. Sometimes- this was really annoying- it left out the one problem that was worked different from all the others. Once in a while, it did have an even problem worked out.

At the beginning of each section there is a study guide with formulas and overall suggestions for working problems in that section. I never really used this part of the solutions manual.

If I had the option to buy this book again, I wouldn't pay what I did pay for it. I paid 27 dollars, with shipping. I think its worth at most maybe 10 dollars, and that's being very generous. If you do decide to buy it, buy it with some friends who are also in your class so you can lessen the cost.
