If you are purchasing the textbook for someone other than yourself, we strongly encourage you to purchase a product with a Download Code which provides you a code to give to another person. That person will enter the code during checkout which allows them to download their own copy of the textbook (with no further payment needed) and receive updates to the PDF for life.

This book is the only one this reviewer is aware of that presents differential equations in a modeling context rather than merely adding a bit of modeling to the standard presentation. If you want to study the mathematics of differential equations in a modeling context, you are in the right place.
