Homework:

 

Graded and ungraded homework will be assigned for each section we cover in class.  It is your responsibility to get the homework from this website and complete all assigned problems.  This is the minimum; you are encouraged to try other problems for further practice.  You are also expected to read all sections that we cover in class.

 

Ungraded homework will be the subject of daily quizzes.  Graded homework will be collected (on paper; no electronic submissions) at the BEGINNING of class as indicated below.  Homework must be written neatly, explained completely, and stapled if you turn in more than one piece of paper.  Problems must be presented in order.  Work not satsifying these criteria will be penalized.

 

You are encouraged to discuss the mathematics behind homework questions with others, but you must write the answer to each question by yourself.  Stated another way, you may only work on the “scratch work” part of a problem with others.  Copying someone else's work (or submitting a proof you wrote with someone else) is cheating, and will not be tolerated.
