In the interest of full disclosure, I graduated from the University of Notre Dame with a BS in Mechanical Engineering having taken 3 semester classes from Professor Goodwine, 2 of them explicity requiring this book. That said, as a professor Goodwine knows quite well what does and does not hold his students attention in a class room. Knowing how to help his students learn (or teach as some might say) translates well into this book. Any one who has ever had to teach themselves out of the book for lack of a gifted professor knows that not all books are created well for this purpose. Should you find your class to be you and this book you will find all the tools you need. There are numerous examples given per chapter, and per topic to help further develop your understanding of the theories and equations that are presented to you.I kept most of my books from college, but this is one of the ones I continue to reference and use. If you wish to remember or learn about differential equations and their applications, this is the book for you.
