Math 442 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 in pen.

  2.  
  3. Homework will be collected on Thursdays at the start of 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.

  4.  
  5. Solutions should be written carefully, using good English, complete sentences, and adequate detail, with citations from the book or notes. Some of these solutions will be explanatory proofs. A good guideline here is that you should write proofs the way you would like to see them in your textbook. In summary,  show all your working to get full marks.
