Title: Vague and Confusing...
Review: When taking an introduction class to differential equations, I found this book to be completely unhelpful in not only mastering the material but simply learning it as well! The explinations in this book are completely confusing and quite wordy. The examples and figures shown within these explinations often times don't even relate to the problems contained within the section. If a concept was not explained clearly, or not at all in lecture, it was very difficult to go back through the section and learn it with the book. I cannot express in words how frustrated and disappointed I am with this book. I am very upset that my professor selected this book because I know there are better texts out on the market. I also had to waste a lot of money for this wordy pile of drivel.
Is the review positive or negative?
