Attendance: Students
are expected to attend every scheduled class and to be familiar with the
University Class Attendance policy as it appears in the General Catalog. It is the studentÕs responsibility to
keep informed of any announcements, syllabus adjustments or policy changes made
during scheduled classes. Students are expected to behave in accordance with
the Student Code of Conduct and the Code of Academic Integrity. The guiding
principle of academic integrity is that a student's submitted work must be the
student's own. University policies can be found at http://deanofstudents.arizona.edu/policiesandcodes.
Homework: Homework will be submitted in two formats throughout
the semester. A computer grading
program called WebAssign will be used for problems assigned from the text (scroll to the bottom for more information). Hand-written
homework showing all work with proper notation will also be submitted when
required. A final homework score based on 75 possible points will be
assigned. Homework is an essential component of the course, whether it is
assigned for grading or not.
Quizzes: Short in class quizzes will be given every class when
possible. No calculators are allowed unless otherwise announced. There are no
make-up quizzes. Some quizzes
will be dropped. A final quiz score of 25 points will be assigned.
In-Class Exams: The
four in-class exams are scheduled for Wednesday, September 14; Wednesday, October 12; Friday, November 4; and Friday,
December 2. The total points for
the exams will be 300 points. All electronic devices, particularly cell phones,
must be turned off during all exams. Silence and vibration modes are not
allowed.
Missed Exam Policy: In general, there will be no make-up exams in the
course. However, in complex and unusual circumstances which are beyond control,
a make-up exam may be given on a case-by-case basis. This will require
providing a detailed account of the situation and any supporting documents.
Approval in these cases is at the sole discretion of the instructor and/or the
dean of students.
Final Exam: The final exam is a common department exam worth 200
points. It is scheduled for Monday, December 12 from 8:00 – 10:00 am. Additional information and a study guide
can be found at http://math.arizona.edu/~calc. The UniversityÕs Exam regulations will be strictly
followed (see http://www.registrar.arizona.edu/schedule111/exams/examrules.htm).
Calculators: A
graphing calculator is an important tool that will be used in this course. Students are expected to have a working
calculator for each exam. No
calculator swapping is permitted during exams. Calculator programs can be found
at http://math.arizona.edu/~krawczyk/calcul.html.

total number of points available on tests and homework is 600. Grades will be no lower than those set

The Department of Mathematics
Undergraduate Committee recently adopted a new policy that a grade of C or
better in Math 129 is a necessary prerequisite for Math 215 (Linear Algebra),
Math 223 (Vector Calculus) or Math 254 (Differential Equations). This
policy will take effect for classes that start in the Fall 2010 semester. Students who receive a D in Math
129 will receive credit for the course towards graduation requirements, but
will not be automatically qualified to register for Math 215, 223 or 254.

related to the format or requirements of this course, please meet with your
