Prerequisite: Math 131A or
REQUIREMENTS: You are responsible
for carefully reading the following and being aware of
all the requirements. Please ask questions about
anything you don't understand.
I want you to enjoy this class,
but please respect my right to teach and your
classmates' rights to learn.
- Please refrain from disruptive
behavior (such as unnecessary talking).
- Laptop/tablet use is restricted to
taking notes. Your cell phones must be turned off
(this in particular means you cannot use your cell
phones in class). Also no reading newspapers
and other non-class materials.
Homework: HW assigned each week will
be due on the following Tuesday at the beginning of
discussion. For example, the HW assigned on Mon 4/1, Wed 4/3, and Fri 4/5
are due on Tues 4/9. See the class
- Weekly HW: 25%
- Midterm: 25%
- Final Exam: 50%
- We will NOT grade the entire HW;
rather a subset of the HW will be chosen and
- You may work with others, consult
other textbooks, and look up resources online
(although I don't recommend it) but the HW you turn in
must be written by you, in
your own words, and you must cite your sources
used and your collaborators. Any HW without proper attribution or not
written in your own words will be considered
plagiarized and will automatically receive a 0, and
you may be subject to disciplinary action depending on
the severity of the infraction.
- Please pay attention to your
writing: The solutions you submit must be clean
(i.e., no rambling discussions and the logical order
should be clear) and complete. Even if you have
the right idea, if we do not understand what you
write, points will be taken off.
Midterms: There will be one
in-class midterm exam during the quarter (Friday, May
3). No makeup midterms
will be given. Any absence on a midterm will
result in a score of 0, unless excused. In case of
an excused absence, the final exam grade will replace
the midterm grade that is missed. It is your responsibility to let me know in
advance if you will be absent for a legitimate
reason, so I can excuse you. In case of an
emergency (e.g., sudden illness), please supply some
documentation afterwards (e.g., doctor's note). If
you have any conflicts with the midterm, please
come talk to me about it within the first two
weeks of class.
Final Exam: Monday, June
The instructor strongly adheres
to the University policies regarding academic integrity
violations, and will strictly enforce these rules. You
are encouraged to review the UCLA
Student Conduct Code.
Students with Disabilities
Any student requesting academic
accommodations based on a disability is required to
register with the Center
for Accessible Education (CAE).
