Participation: Throughout the course of the semester
there will be an undisclosed number of participation assignments given
in class on undisclosed dates. The purpose of these assignments is not
to assess your understanding of any concepts. Rather, the purpose of
the participation assignments is to allow you to work through problems
in class (so that we can identify which concepts need more attention
and make the appropriate changes together). In most cases, if you show
up to class on time and stay for the duration of the class period on
the day a participation assignment is given, you will receive full
credit (3 points) for the assignment.
Attendance
Policy: It is imperative that you attend every
lecture and stay for the lectures full duration. Because the material
is difficult to learn on your own, very few students can succeed in
this course without attending lecture. Please notify me in advance if
you are going to miss part or all of a class so that we can make a plan
to keep you on track
Homework:
All assignments will be collected
every
Friday in class and only a few questions in each
assignment will be graded. Late homework will not be accepted. I will
update these problems after each class meeting. Please make sure to refresh the webpage

Study Hint:
Find at least one or two other
students from the class with whom you can regularly do homework and
prepare for exams. Your classmates are perhaps the least used and
arguably your best resource. An efficient and effective study group
will streamline homework and study time and greatly improve your
written and spoken communication. The best time to use your classmates as
study/homework partners is after you have made an honest effort on
your own to solve the problems using your own wits, knowledge, and
experience. When you encounter an unsolvable problem, don't give up too
soon on it. Being stumped is an opportunity for mathematical growth and
insight, even if you never solve the problem on your own. If you seek
help prematurely, you will never know if you could have solved a tough
problem without outside assistance.
