HOMEWORK
MTH 679 — Spring 2016
Ground Rules
-
Suggested Reading
-
It is to your advantage to skim suggested readings as soon as possible.
However, do not expect to master this material the first time around. Don't
worry; we'll cover it in class, after which the readings should make more
sense. But be warned: we will not always cover the material the same way it
is presented in the books.
-
Written Work
-
It is your job to explain your work to me clearly and completely. Here are
some guidelines:
-
Write legibly, or use a word processor;
-
Do not use scratch paper;
-
Explain at least briefly what you're trying to do, don't just do it;
-
Use complete sentences;
-
Equations should (mostly) be contained in sentences;
-
Feel free to use technology when appropriate, but this must be clearly
documented. If possible, attach a printout of your session, together with a
brief explanation of what you did.
You may discuss homework problems with anyone you like, and you may use any
reference materials you like. However, you must write up the solutions
in your own words, and you must indicate what help you used.
Late homework will be corrected as a courtesy to you, but can earn at most
half credit.
