MA240 homework

All problems are from Differential Equations with Boundary-Value Problems by Dennis Zill, Warren Wright and Michael Cullen (8th ed.)

As specified in the course syllabus, you may work individually or in groups of at most three students. A group must make a single joint submission with all team members listed at the top of the first page. In the case of a group submission all members will receive the same grade for the assignment. You should make sure you understand all the solutions your team is submitting, even if other team members came up with them. If your team receives any outside assistance, that assistance must be explicitly acknowledged (otherwise your team is submitting the work or ideas of someone else as its own, i.e. committing plagiarism). You are not required to work with the same team throughout the term. Teams may be formed on an assignment-by-assignment basis.

Homework assignments must be submitted at the beginning of the class period on the assignment due date. Each assignment includes all problems from the list below not previously submitted up to and including those pertaining to the last section completed during the last class meeting prior to the assignment due date. Credit will not be awarded for late submissions... but your lowest homework score will be dropped.

Problems which require a computer algebra system are highly recommended, but may be omitted from submissions.
