Now enhanced with the innovative DE Tools CD-ROM and the iLrn teaching and learning system, this proven text explains the "how" behind the material and strikes a balance between the analytical, qualitative, and quantitative approaches to the study of differential equations. This accessible text speaks to students through a wealth of pedagogical aids, including an abundance of examples, explanations, "Remarks" boxes, definitions, and group projects. Author Dennis G. Zill wrote this book with the student's understanding kept firmly in mind. He presents the material in a straightforward, readable, and helpful manner, while keeping the level of theory consistent with the notion of a "first course."

I've used two different texts for a refresher course in differential equations. This is the better of the two The text is clear; the printing and formatting are well done and the problems are well-organized with progressive difficulty.
However, I'm bothered by the number of errors in even the example problems. Some chapters have several errors - mostly incorrect signs and simple addition/subtraction errors. But as those errors get propagated in these sorts of problems, the consequences can lead to very different solutions.
