## Course Policy

1. You must be on the class roster by January 26, 2009 to participate in any way (attend class,
submit homework, take quizzes, take tests).

2. Attendance is required by University rules . If you have to miss a class, you are responsible
for any missed class notes, or assignments.

3. Students are expected to comport themselves as adults, and to follow all University Rules,
Regulations and Policies, including those on discipline, academic honesty, and harassment.
Disruptions, including inappropriate language, are unacceptable. Cell phones and beepers
should be turned off during class.

4. The prerequisite for this course is a grade of C- or better in 3450:223 Analytic Geometry –
Calculus III, or the equivalent . Students who do not meet the prerequisite are liable to be
withdrawn from the course.

5. Important Dates :
January 12, 2009 – classes begin
January 19, 2009 – Martin Luther King Day, no classes
January 26, 2009 – last day to withdraw without advisor’ s signature
March 6, 2009 – last day to withdraw without instructor’s signature
March 14 – March 20, 2009 – Spring Break, no classes
April 10, 2009 (5:00pm) – last day to withdraw from courses
May 1, 2009 – last day of class
May 4, 2009 – Final Examination 8:00–9:55am, room to be announced

6. Incompletes will only be given in documentable cases of long- term illness , or similar problems.
In addition, at least half of the semester’s work must have been completed, with at
least an average grade of C. College policy also states that a student may not sit in on the
course the next semester to make up the incomplete, but only to make up the missed work.

7. There is a recommended list of homework problems given for each section. You should do as
many as necessary to gain mastery of the material. These homeworks will not be collected.
There will be additional homeworks assigned, and collected, usually on Wednesday. Each
homework question will be graded out of 5 points. No late homework will be accepted.
All work submitted must be your own. Neatness and and other communication
skills, including spelling, count.
Some homeworks will be dropped to compute your final
score. There may also be quizzes given.

8. If you are going to miss a test (which will be announced approximately one week in advance),
you must have a valid, documentable excuse and notify me in advance, or as soon as
reasonable afterward. The make-up will be as soon as possible, generally within a week of the
original test date.

9. Final grades will be determined from 450 points, broken down as follows : 2 exams @ 100
points each, homework/quizzes @ 100 points, comprehensive final exam @ 150 points.

The final scale used will be no higher than A 90-100%, B 80-90%, C 70-80%, D 60-70%, F
0-60%. Plus and minus grades will be given at my discretion.
