Guidelines for writing and submitting your homework:
- Show all work. Write clearly and legibly, in complete sentences. For full credit, your solutions
need to be not only correct but also clearly explained.
- Do all problems in sequence if possible.
For each solution, identify clearly the section and problem number
(e.g. 11.2, 11.30). Staple your assignment.
- You may discuss the
homework with other students, but the final write-up must be your own.
-
If you cannot come to class, ask a friend to hand in your assignment
or drop it off at your instructor's office before 12 noon on the due date.
Late homework will not be accepted. Answers/solutions will be posted immediately after class.
