1/21/02 TAKE-HOME
QUIZZES for MATH 3200: Elementary Differential Equations
TAKE-HOME QUIZZES: There are 10 quizzes containing roughly 110
textbook problems in all. Each problem
is worth 2 points except for chapter 3 problems that are worth 4 points
each. Of the roughly 240 possible
points, 200 points (28.6% of your grade) count toward your final grade. That is, once 200 points are reached, any
points that are made do not count toward your grade. Students are encouraged to work together in cooperative groups on
the take-home quizzes; however, each person must turn in her/his own quiz. I expect each student to obtain the full 200
points.
The problems for the sections to be turned
in will be confirmed on the Thursday before the Tuesday on which they are
due. If you skip class, please make
sure you check with a classmate to make sure that the problems that you are to
turn in are actually due. Alternatively,
I will not ask for more problems than what are scheduled so that you can always
turn in the problems that are listed in this syllabus as being due and you will
always be safe. You may be turning more
problems than necessary, but you will never turn in fewer problems than
necessary. If you turn in more problems
than necessary, I will simply return these to you to turn in with your next
quiz.
Quizzes are due on the Tuesdays listed. You are free to turn in your quiz on the
following Thursday, at the beginning of class with no penalty. After 10am on Thursday, quizzes are not
accepted. If you are unable to turn in
your quiz (regardless of the reason), the extra points are to be used for just
such occasions. So simply use them this
way without asking. If you miss several
weeks legitimately, then we will have to find a way to make up the
missed work.
You are always to show your work
sufficient for me to understand how you obtained your answer. You are to show your work even if the
textbook does not require it. If you do
your problems using a computer system (like derive, scientific notebook or
maple), you must attach a hardcopy of what you did to obtain your answer. If you are using a powerful scientific
calculator, you will have to show your work as if you did it by hand using the
calculator to make sure your answer is correct unless you can get a hardcopy
printout of what your calculator did to give you the solution. If you are graphing by hand, you are to make
sure that you put in a number scale on both axes. Please make hand-drawn graphs as neat as possible. Format: Please staple your
take-home quizzes. If your quiz is not
stapled, you will be assessed 2 points.
I do not carry a stapler with me.
Please turn in a neatly written assignment.
