Here is a sample problem from our book, together with a PDF image of a Mathematica solution. If your browser is configured to view Mathematica Notebooks, you can view the actual Mathematica Notebook solution.
This book was written as a supplement to Elementary Differential Equations by Boyce & DiPrima (also published by Wiley); it can also be used with most other sophomore level ODE texts. The Mathematica version is available bundled with Boyce & DiPrima's book.
