# Math 442 Assignments

### General remarks

- 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.

- 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.

- 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.
