Final
exam: 40%
Midterms: 20% each
A
provisional schedule with homework assignments is indicated below; it will be
updated regularly. You can find a
sample syllabus, with reading assignments, at this
page. More complete
information about the course is on the department's Calculus
III page.
Textbook: The course textbook is James Stewart, Calculus: Early Transcendentals (8th edition)
WebAssign: WebAssign will not be required for the course. However, students who wish to take
advantage of features of WebAssign can use the class key
columbia 8235 9880
Prerequisites: The sole prerequisite for the course is Calculus I. Familiarity with the material of
Calculus II is helpful but not essential.

Final exam schedule: (see
above)
If you have a conflict with
any of the exams, you must inform the instructor as soon as possible and at
least one month before the exam. Makeup exams
will not be given unless the student has two other exams scheduled the same
day. Students with three exams
scheduled on the same day should visit the Student Service Center in 205 Kent
Hall to fill out a form which can then be submitted to each instructor or
department. An attempt will then
be made to arrange for one of the instructors to schedule a makeup exam on a
different day. Students can only
be excused from the exams because of serious illness or family emergency; documentation from your doctor or dean
must be provided.
No electronic devices (laptops,
calculators, telephones) are allowed during exams.
Academic integrity:
Students are encouraged to work together on homework but any assignments
handed in should be the work of the person whose name appears at the top of the
page. Collaboration during exams
is considered cheating and is taken very seriously. Cheating during a midterm or final entails failing the
course. Students are advised to
consult the Columbia
University Undergraduate Guide to Academic Integrity.
Disability services:
In order to ensure their rights to reasonable accommodations, it is the
responsibility of students to report any learningrelated disabilities, to do
so in a timely fashion, and to do so through the Office of Disability Services.
Students who have documented conditions and are determined by DS to need
individualized services will be provided an DScertified ‘Accommodation
Letter’. It is students’ responsibility to provide this letter to all their
instructors and in so doing request the stated accommodations.
More information on the DS
registration process is available online at https://health.columbia.edu/content/disabilityservices.
