Homework Guidelines

(Based on guidelines kindly provided by John Eggers.)

1. Which problems to hand in
• Only submit those homework problems that are posted in the TritonEd Content area (not yet posted)
• The exercises listed on this webpage are for practice. You should do them all, but you will not hand them in/submit them for a grade
2. Format Guidelines
   • Type your solutions up (preferably using LaTeX).
   • Submit your assignment via Gradescope as a PDF file.
   • Be sure to include your name prominently in your document.
   • Here is a checklist written by a former TA that you might find helpful.
3. Punctuality Guidelines
   • Submit your assignment via Gradescope before the date due.
   • Late assignments will only be accepted under extraordinary circumstances.
   • Acceptance of late assignments requires the consent of the instructor.
   • Requests to submit a late assignment will be denied if made more than one day past the due date.
   • Homework assignments are due at 8:00 A.M. on Tuesdays. Revisions are due at 11:00 P.M. on Thursdays. These deadlines may alter due to circumstances beyond the instructor's control. Whatever due date and time are given in Gradescope are the correct due date and time.
4. Attribution Guidelines
   • You may consult any book, periodical, website, or person for assistance.
   • Give credit to any book, periodical, website, or person from which you obtained assistance. (Note: You need not mention assistance from the professor, TA, or mentors.)
     Examples:
     • Mary Jones told you the main idea for proof in problem 1.1. You would write something like: "Mary Smith told me the main idea for this proof."
     • You found the solution to problem 2.1 in "Naive Set Theory" by Paul Halmos. You would write something like: "I found this solution in Naive Set Theory by Paul Halmos."
   • There is no penalty for finding a solution in a book or website, or getting it from a friend; however, failing to give credit to the book or website, or your friend would not be honest and could be considered plagiarism. Celebrate your sources by honoring them!
   • It is, of course, to your benefit to discover and work out as many of the solutions for yourself as possible; however, research and discussion with peers is a very helpful part of the learning process.
