Homework

The homework should be handed in before the start of Friday lecture. It must be legible, and written in connected sentences that explains what you are doing. Just the answer (whether correct or not) is not enough. ease put your name on every page and staple the pages together. Homework should be handed in on time, late homework will not be graded.

Though it is fine to discuss the HW problems with others, you must always write up the solutions in your own words. Copying will be penalized. Of course, in the exams you must work on your own: no calculators, textbooks etc will be allowed.
