Elementary Differential Equations and Boundary Value Problems,    by Boyce, DiPrima, and Meade

The downloadable files below, in PDF format, contain answers to all the problems from the textbook (11th edition). Extensive MATLAB code snippets are included in many of the problems, and may be accessed and copied from the PDF file using standard computer copy-and-paste procedures (e.g., Ctrl-C of the highlighted code). Chapters 1 - 10 are available now. The last chapter will be added in the future.

To download an individual chapter PDF file to your computer, click on a chapter heading below, and then save the file when prompted. Or, to download the entire solution set in one file (160 MB), click on the "Combined Solutions" link below.
