Review title: Terrible and Full of Mistakes Product review: I bought this text thinking it would be a succinct and useful review of the core fundamentals of engineering--it is anything but that.It appears that nobody bothered to proofread this text before printing it, as it is full of errors ranging from misnumbered or completely missing equations and references to problem solutions solved using different values than those provided in the problem statement or that are just fundamentally wrong. The dynamics section and circuits section are the worst I have encountered so far, but I expect to find more mistakes before I finish looking through the text.Having prepared for several standardized tests in the last two years, I can say with certainty that this is the worst review text I have ever purchased. Do not buy this book unless you like to be confused and irritated or like to correct someone else's mistakes.
Ans: decrease

Review title: Pretty decent numerical book. Good if you use Matlab Product review: I liked this book. It covers a large variety of subjects. It has some good examples, and gives you practice problems to work on. It has solutions to many odd problems in the back of the book. Good if you're self studying on your own. The author also provides good explainations of numerical techniques. Could used more examples for Matlab, but provides enough to get reader into the more detailed functions.There are some errors in the literature. If you're comfortable with numerical techniques, you should find them. Most of the book is safe to use.I got the book on a good discount, and find it being used more than the other numerical books in the library (for Matlab and non-Matlab languages).Books rarely get a 5, but this one surely deserves a 4.

Review title: One of the best books I have ever read! Product review: Barbara Delinsky just continues to improve with each book! I anxiously await her novels, as they are an absolute joy to read! I find that once I start reading her books, I can't put them down until I turn the last page and then I am sad that the book is over! Thank you, Barbara, for sharing your talent with so many of us! This book left me with a deep impression - it was definitely one of your best! I am already looking forward to reading your next novel...hope the wait is not long! You have the ability to relate to your readers in a very special way!
