Announcements
- Everyone who asked for grades by email should have them by now. A histogram added to the solutions.
- 12:26, 14 December, 2010. It will be mid-afternoon today before I finish the grades.
- I put up solutions to the final -- this is before reading your solutions so I may add a few more alternatives tomorrow. Grades should be available by around 12:30 tomorrow if you want to ask (for instance by email). 13 December, 2010.
- Have fun tomorrow -- don't forget to do the evaluation before the end of today -- Sunday (or maybe early tomorrow). Try to get the right exam paper, the one for Section 1, Melrose.
Old announcements
Analysis 1, 18.100*
- 18.100A Taught this semester by Arthur Mattuck is a
somewhat less demanding course, still giving a rigorous introduction to
analysis but not including general metric spaces. If you are going to switch
from 18.100B to 18.100A you should do it as early as possible since there is no
coordination between these courses and different texts are used.
- 18.100B has two sections, this website is for Section 1. For
Section 2, of 18.100B, lectures by Katrin Wehrheim, go to
the Stellar
page for 18.100B. Note that the two sections will be run
independently this semester -- different homeworks, tests and (maybe) final
exams. So if you are going to switch between the sections you should
do it within the first two weeks of the semester. You should go to
the Stellar
page for 18.100B to choose a section and do the appropriate
homework and tests.
- 18.100C is the same course as 18.100B but with a
MANDATORY meeting for an additional hour each week for further
instruction and practice in material related to the communications
requirement. For 18.100C (which can be taken with either section of
100B plus one of the two extra meetings per week) go to the Stellar
page for 18.100C.
To take 18.100C you must register for it but you can attend whichever of the two lecture courses of 100B you wish.
RBM Office hour:W 9:30AM-11AM in Room 2-174
You can ask me about the lectures (you can do that during lectures too
of course) or about the homework or we can talk about something even
more interesting. You are welcome to email me questions -- to rbm at
math dot mit dot edu -- and you will likely get an answer!

Text and aim of the course
Walter Rudin: Principles of Analysis. Due to the idiotic copyright
laws a new version costs a bundle. You should be able to pick up a
second-hand copy for much less -- or there are `international
editions' of unknown (to me) legality for even less. You can also
probably find scanned copies, but I would guess that these are simply
illegal.
The book itself you might find hard reading since it is very much the
opposite of a bloated calculus textbook. Don't worry if you need to
spend several hours on a page! Apart from going through most of
one-variable calculus rigorously, a primary aim of the course is to
ensure that students can write clearly and concisely. In particular it
is not enough to blunder across `the correct answer', it is just as
important to understand why things are true. See the comments on final
grades below.
Beyond calculus of one variable -- functions, differentiability and
(Riemann) integrability -- we will talk about metric spaces. These are
a very important class of topological spaces -- so the notion of
continuity is defined for maps between metric spaces -- which are
important in many areas of mathematics. The course is intended as a
gateway to other undergraduate and hence to graduate courses. After
taking this course you can take for instance 101, 102, 103,
112, 701, 901.
Homework and Tests
Homework will be due on Thursdays. Paper homework must be put in the
tray in 2-108, marked 18.100B Melrose, by 11AM on Thursdays -- or
given to me in lecture -- since I will pick it up after the
lecture. No late paper homework will be accepted. Either TeX output or
scanned-to-pdf files can be emailed to me (and only me, not the
grader) at rbm at math dot mit dot edu any time up to 5PM on the
Thursday on which it is due. Late homework will be accepted in
electronic form only -- so it is late if it arrives after 5PM -- it
will be graded but marks will be deducted according to a scheme that
will remain private.
Solutions will be posted on Thursday evenings.
About collaboration etc. I don't much mind how you go about learning
and doing the homework is supposed to be part of that, but I draw the
line somewhere short of copying from someone, or somewhere, else. It
is fine if someone explains it to you, or if you read someone else's
solutions, but you should produce your own version.

Final Grades
Final grades for 18.100B, for people in Section 1, will be computed in two distinct ways and the actual grade will be the better of the two.
- Method 1. Accumulated Homework grade to 30%, In-class tests 30%, Final 40%.
- Method 2. Just based on the final exam.
I do not suggest relying on the second method!
Final grades for 18.100C are computed based on required
attendence at the weekly `recitation' and given that, the 18.100B
component forms 80% of the total.
Meaning of grades:
- A+,A,A-. Full to essential mastery of the subject.
- B+,B,B-. Clear to somewhat patchy understanding of the material.
- C+,C,C-. Partial to marginal comprehension.
- D,F. Tried a bit to did not attend.
I have found the only really hard separating lines to draw are usually A+/A and
A-/B+. I don't mind if every one gets an A+ since they will have earned it.
