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.

1 out of 5 starsNot so helpful, 2009-06-30
Like other people have said, this solutions guide is unlike every other solutions guide in the universe. It doesn't have solutions for all the odd problems. It really doesn't have any solutions at all. It only half works out the problems it does have. You can't see how they got where they are. If I knew all the steps I wouldn't have bought a solutions guide. Nothing is actually worked out problem wise. It just writes solutions like you're writing an essay. Not a good buy. There are better resources for less on the web.

The description of the quality for the book was exactly right, and it was very fast.
