MATH 365 Homework Solutions

This page contains links to homework solutions from Elementary Differential Equations and Boundary Value Problems, 7th edition, by Boyce and DiPrima. Before looking at the solutions, there are a few things you should keep in mind.

These solutions were written out by hand in pencil and then scanned. The images are neither clean nor sharp. If someone would like to type them into LaTeX, I would much appreciate the help.
You should try very hard to solve the exercises yourself before looking at my answers. You will learn by trying even if you do not immediately find the answers.
I am only human. You may find errors in my homework solutions. If you do, please email me the section and problem number and I will try to fix the error.
