Course Content |
Differentiation. Riemann integral. Sequences and series of
functions. Special functions. Fourier series. This corresponds to chapters
5-8 in Rudin's book.
|
Prerequisities: | Math 140A or permission of
instructor. Students will not receive credit for both Math 140 and
Math 142. Math 140
is a difficult and time consuming course, so enroll only if your course
load allows it. |
Grade Breakdown | The grade is computed as the
best of the following
weighed averages:
- Homework 20%, Midterm I 20%, Midterm II
20%,
Final Exam 40%
- Homework 20%, Midterm I 15%, Midterm II 15%, Final Exam 50%
|
Textbook: | W. Rudin, Principles of Mathematical
Analysis, Third Edition. |
Readings | Reading the sections of the textbook
corresponding to
the assigned homework exercises is considered part of the homework
assignment. You are responsible for material in the assigned reading
whether or not it is discussed in the lecture. It will be expected that
you read the assigned material in advance of each lecture. |
Homework |
Homework problems will be assigned on the
course
homework
page. There will be 7 problem sets, typically due on Friday at
4:30PM
in
the TA's mailbox. The due date
of some of the problem sets may
change during the quarter depending on the pace at which we cover the
relevant topics. The best six problem sets will be used to compute
the
final grade.
You may work together with your classmates on your
homework
and/or ask the TA (or myself) for
help on assigned homework problems. However, the work you turn in must be
your own. No late homework assignments will be accepted.

Midterm Exams | There will be two midterm exams given
on April 26 and May 19. There will be no makeup
exams.
Regrading policy: graded exams will be handed back in
section.
Regrading is not possible after the exam leaves
the room.
|
Final Exam | The final examination will be held on
Friday, June 16, 3:00-6:00PM. There is no
make up final
examination. It is your responsability
to ensure that you do not have a schedule conflict during the final
examination; you should not enroll in this class if you cannot
sit for the final examination at its scheduled time. |
