Prerequisite: One of Math 215,
Math 255 or Math 265.
- Jan. 4. There is a change to the two midterm
dates (Feb 11 and March 18)
and HW submission dates (Wednesdays,
starting from Jan 12) and. See below.
- Jan 4. HW 1 is now posted. Due, Wed, Jan 11.
- Jan 6 (Friday). HW 1 Problem 6 will NOT be graded. (That is, only Problems 1, 2, 3, 4, 5 will be graded.)
- Jan 12. Office hours are set-up: Mondays 2pm-- 3:50pm at Math 235
- Jan 12. HW 2 is now posted. HW 1 solution set is now posted.
- Jan 12. Review power series. Be familiar with the operations with
them. see e.g.
- Jan 24. Typo in the notes Lecture
10. page 51 in equation (8.2). It should be read as " ........=
Constant = - \lambda^2" <--- Here, \lambda means the Greek letter
'lambda' and ^2 means sqaure.
- Jan 28. Please parcitapate in the
survey. The link is here http://www.surveymonkey.com/s/85Z7YBS
the password I have
sent to you in a separate email. This survey will be closed on
Wednesday. Your participation is important for us.
- Feb 11. Final exam date is now decided. Tue APR 19, 3:30pm,
(duration 150min.) Location to be determined.
- March 1. There was a typo/mistake in HW 6, Problem 4(b). The
corrected HW is now posted. For Problem 4 (b), you can hand in it in
the class on Friday, March 4. For other problems (up to Problem 4 (a)),
the due date is Wed, March 2.

Final Grading Scheme: The
higher one in
- HW including spreadsheet projects (15%), Two Midterms
Final exam (50%)
- HW including spreadsheet project (15%), Best of Two
(15%), Final exam (70%)
- Homework will be collected at the beginning of lecture each Wednesday
starting on Jan 12.
for example, I will NOT accept homework submission at my office.
This policy is to motivate students keep attending the lectures.
will not be accepted.
A missed homework will result in 0 mark.
homework grades will be
dropped in computing the final grade.
- Your homework should be written in a clear manner so that the
grader can understand easily
what you are doing. Also it should
be handwritten neatly. Unreadable or very hard to read
homework may get zero or very low mark.
- You are encouraged to discuss the homework with other students,
but you must produce and write the solutions on your own.
- It is probable that only a subset of those problems turned in
graded, and you will not be informed (in advance) which ones these are.
For example, if your homework does
not contain any of the problems
to be graded (which will be decided after the deadline), you will get
zero mark. So, it would be better for you to do all the problems
Marking policy (especially
for the exams):
- The midterms
will be held during
class hours on February 11
(Friday) and March 18 (Friday).
- No make-up midterms!
- Missing a midterm normally results
in a mark of 0. Exceptions may be granted ONLY with
prior consent of the instructor, and with ofﬁcial documentation
supporting the student’s reason for
missing the exam. In case of a medical emergency, the instructor must
be notiﬁed within 48 hours
of the missed test, and presented with a doctor’s note immediately upon
the students return to UBC.
A physician’s note should speciﬁcally state that the student was
medically unﬁt to write the missed
exam on that speciﬁc day.
- The date of
the ﬁnal exam is yet to be declared. Do not make any travel plans until
the exam schedule
has been announced.
- IT IS ESPECIALLY
IMPORTANT that students know that IF THEY DO NOT FULFILL THE COURSE
REQUIREMENTS DURING THE TERM (including not writing the midterm
test(s) even if you agree to transfer the weight to the final) AND THEN MISS THE FINAL EXAMINATION, THEY
MAY BE DEEMED INELIGIBLE FOR A DEFERRED FINAL.
- Students will
be required to bring Photo
- Calculators, books,
or aids of any kind will NOT be allowed in midterms or in the
midterm exams should be made right at the time you get the
exam back. Later claims will NOT
For computational problems, to earn lots of credit, you have to
get the right answer with proper set-up of the calculation.
In many cases (especially for the easier problems), about half
the points will be given for setting up the calculation properly and about half for
computing the numerical answer correctly.
For more difficult problems, more percentage will be given for properly
setting-up the calculation. You
may loose most (sometimes, all) of points for setting up the calculation incorrectly,
even if the subsequent computations are correct. Also, you may
loose half the points for not finding the correct final answer, even if
the initial set-up is correct.
