Math 342 Assignments

General remarks

  1. Homework should be legible and neat, questions should be answered in order, and pages should be fastened with a staple with your name and student number on at least the front page.

    2.  
  2. Homework will be collected on Thursdays in class and will cover the material through Tuesday's lecture (roughly). You should start attempting the problems as soon as possible after the material is presented in lecture. Please don't save it all for Wednesday night.

    3.  
  3. Solutions should be written carefully, using good English, complete sentences, and adequate detail, with citations from the book or notes. Some of these solutions may be proofs. A good guideline here is that you should write proofs the way you would like to see them in your textbook.

    4.  
  4. Some of the problems have hints in the back of the book. If you get stuck on a problem, you might find it helpful to look at a nearby unassigned problem that has a hint.
