Math 42 Winter 2014 
Math 42 Winter 2014This sheet is not a complete syllabus  instead find everything online at http://math42.stanford.edu, along with our first assignment of Daily Discussion Problems for this Tuesday's sections. 

Math 42 is a 5unit secondterm course in calculus with an accelerated pace  the class covers techniques
of integration, applications of integration, differential equations,
infinite sequences and series, and Taylor polynomials. Although everyone
is welcome in the course, it is aimed primarily to students who took
Math 41 last quarter (or have equivalent preparation) and will continue
taking more advanced quantitative classes which require a strong calculus
background.
There are at least
two other math courses which may be appropriate for students considering
Math 42, so you should be deciding in the first week or so whether Math 42
is the right class for you.
If you successfully took Math 41 last quarter and wish to continue studying
calculus, either as background for other subjects or purely out of interest,
then Math 42 should be the best class for you.
However, be warned that Math 42 moves just as quickly as Math 41 but covers
more difficult material. So you can expect Math 42 to be more work than
Math 41 was, especially if you had calculus in high school and that background
helped you through Math 41.
If you didn't take Math 41 last quarter, you should consider taking Math 20
instead. This is especially true if you are taking math purely
out of interest or to satisfy a GER and don't plan to take Math 51 or other
more advanced classes  even if you did well in calculus in high school.
The sequence Math 192021 covers the same material as Math 4142, but at the more traditional yearlong pace (ending with Math 21 in the spring quarter).
The nonaccelerated pace of Math 20 makes
it easier for students who have been away from calculus for a while to get
their feet under them, and the 3unit workload may be preferable to
students who don't plan to continue taking math courses.
Completing Math 21 also gives you the
appropriate background to take Math 51 if you choose to do so later.
One quick headsup to those who didn't take Math 41 and do decide to take
Math 42 this quarter: Math 41 last quarter covered a couple of topics which
are not on the Calculus AB syllabus, and which you therefore may not have
seen in high school. In particular, we covered l'Hospital's Rule (which
will not be discussed much in Math 42, but will come up in passing) and
integration by parts (which will be treated as a review topic at the
very beginning of Math 42).
Finally, to any students who have already seen and are comfortable with most
of the material in Math 42, but don't feel quite ready for Math 51: you should
know that Math 42 and Math 51 cover very different material, and seeing the
material in Math 42 again will not substantially improve your preparation for
Math 51. You're probably better off diving right into Math 51.
On Registrar deadlines: Please pay careful attention to all Registrar deadlines, especially the add/drop deadline at the end of the third week of classes. However, University Advising and Research has a special provision in place to accept petitions for switches from Math 42 to 20 submitted in complete form before Friday, February 7, 2014, at 5pm. The instructions for how to properly complete the petition is contained at the bottom of this page. You can also contact your instructor for more information.

The textbook is Single Variable Calculus: Concepts and Contexts, 4th
edition, by James Stewart.
This is the same textbook used in Math 41 last fall (and it is also used by Math 19, 20, and 21).
We will cover most of the material from the second half of Chapter 5 to the end of the book.
Most homework exercises and reading
assignments are taken from the book, so you should have access to a copy throughout the quarter.
(It is not recommended that you try to use a copy of an older edition: although the text is very similar, some examples, some of the homework problems, and most of the problem numbers will be different.)

Each week you will attend three lectures and two discussion sections. The
lectures are on Monday, Wednesday and Friday, either at 10am, 11am, or 1:15pm.
The discussion sections are on Tuesday and Thursday. See the Section Assignments page to view the choices for times and locations and instructions
on the signup process. You will sign up for a discussion section via CourseWork,
and your available options will depend on your lecture instructor.
The lectures will be used primarily to introduce concepts and develop theory, and serve as a complement to the course textbook. You can get the most out of lecture by having first read the relevant sections in the textbook (as set in the calendar of topics on the course schedule page). In the discussion sections, you meet with your Teaching Assistant in a smaller group. Much of the time in section will be used for example problems based on topics developed in lecture and the textbook; you can get the most out of section by working on the posted daily discussion problems in advance (i.e., immediately after lectures).
Attendance at all lectures and sections is required. If you miss a lecture or a section, it is your responsibility to catch up on the topics that you missed. You should keep in mind that in this course, the material builds on itself; if you miss some of the material, subsequent lectures will be more difficult (or even unintelligible) for you.

There will be weekly homework assignments.
For more information and policies, see the Homework page.

Calculators
Calculators will not be used in a systematic way in Math 42. Calculators will
not be allowed on any of the exams, nor should there be any need for one.
Occasionally, homework problems may call for the use of a scientific or
graphing calculator.

The midterm exams will be held in the evenings on January 28 and
February 20.
The exact times and locations and other information will be posted on the
Exam Information page.
If you have a schedule conflict with one
of the midterm exams due to another course meeting, you must
at least one week before the exam to arrange to take it at an alternate
(early) sitting. (The same deadline holds for OAE accomodation requests; see below for details.)
The final exam will be held on Monday, March 17, from 710pm.
You must take the final exam at this time, which is set by the University.
All of the exams are closed book, closed notes, with no electronic aids.
For each exam, if appropriate, you may be provided with a formula
sheet, which will be available on the exam materials
page prior to the exam, along with other study materials.

Your grade will be based on the following components:
 Weekly Homework: 10%
 Total points earned on all exams (midterms and final): 90%
Points available on exams: The total points available on the exams will be in approximate proportion 2:2:3. That is, the first and second midterm exams will have approximately equal numbers of total points available, and the number of points available on the final exam will be approximately 1.5 times those available on a single midterm exam.
There are no predetermined numerical cutoffs for letter grades, and the cutoffs may turn out to be rather different from what you are accustomed to from high school. In general, the grade distribution for the class is usually (roughly) as follows: around 30% of the class receive A's, around 40% receive B's, and most of the rest receive C's.

CourseWork
CourseWork
is a webbased program that will be used in Math 42 to allow
students to check grades online. It is a secure program, so your grades
will be available through CourseWork only to you.
Every student must sign into CourseWork and choose a discussion section. CourseWork will be
our primary gradekeeping tool; if you do not sign up, you could lose credit
for work that you have done.
This is completely independent of signing up for the course on Axess  neither
program has any knowledge of the other.
Before you sign into CourseWork, make sure you read the
Section Assignments page, which contains instructions on the signup process for
discussion sections.
Again, remember that Axess and CourseWork are different programs, and you
will
sign up for different course components on each  on CourseWork, you sign up for a
discussion section
based on the table on the Section Assignments
page,
but on Axess you sign up
for a lecture.
Despite its other capabilities, in this class CourseWork will be used only
for grades and possibly email announcements.

 Tips for Success in Undergraduate Math Courses by Jessica Purcell
 Some very good advice for college calculus students. Read this carefully and do as it suggests.
Note: Pay particular attention to #3 under "Weekly" and #6 and
#7 under "Before the exam". Students who think they're following these
tips often overlook those parts, and they're the most important
ones!
 Common Errors in Undergraduate Mathematics by Eric Schechter

Although this document is a bit on
the long side, you should read at least some of it carefully 
you'll do better in your math classes because of it.
We encourage you to pay particular attention
to the sections:
bad handwriting,
all of the algebra errors,
streamofconsciousness notations, and
going over your work.
 Math 42 Teaching Staff Office Hours
 Your first resource for help outside of class meetings should be the course instructors and teaching assistants. You are encouraged to attend any of their officehour sessions, not just those for your lecture or section leader, and no appointment is necessary at the times posted. In office hours we welcome any kind of question; we are here to help you and ready to explain the same thing as many times as necessary. You can also email us, but keep in mind that questions in office hours are answered more quickly and more clearly.
 Free Tutoring at the Center for Teaching & Learning (runs Sunday, Jan. 12 through dead week)
 Evening Tutoring by SUMO undergraduate members (free, but priority goes to Math 50series students)
 Math Department Web Page
 Math 42A students are part of the ACE program, short for "Accelerated Calculus for Engineers." More information about the program can be found here.
 Statement from the Registrar concerning students with documented disabilities:
 "Students who may need an academic accommodation based on the impact of a disability must initiate the request with the Office of Accessible Education (OAE). Professional staff will evaluate the request with required documentation, recommend reasonable accommodations, and prepare an Accommodation Letter for faculty dated in the current quarter in which the request is being made. Students should contact the OAE as soon as possible since timely notice is needed to coordinate accommodations. The OAE is located at 563 Salvatierra Walk (phone: 7231066)."
 Honor Code and Fundamental Standard
 By Math Department policy, any student found to be in violation of the Honor Code on any assignment or exam in this course will receive a final course letter grade of NP.
 Statement from Undergraduate Advising and Research concerning the special provision for fifthweek switch to Math 20:
 "Any student registered for either MATH 42 or MATH 42A who wishes to switch to MATH 20 after the Add/Drop Deadline may do so by submitting a Petition to Change Course Enrollment no later than 5:00pm on Friday, February 7, 2014. Students will receive full credit for MATH 20 (3 units) upon earning a passing grade for that course. (Students switching from MATH 42A to MATH 20 may also add the 1unit ACE course EE 191, before the above date.)
 "Note: Because of the discrepancy in units between either MATH 42 (5 units) or MATH 42A (6 units), and MATH 20 (3 units), students should be advised to consider the possible impact this change may have on their university enrollment requirements. For this reason, students switching from either MATH 42/42A must meet with a UAR Advisor.
 "Specifically, students should complete the Petition to Change Course Enrollment form in the following manner:
 Complete the personal information section.
 Select 'Section change' and enter the information for both courses in the Change Requested section.
 Obtain signature from the instructor of the new course (MATH 20). This may require advance notice of 12 days, so prompt attention to this is imperative.
[See "additional details" below for contacting Math 20 instructors.]
(Students switching from MATH 42A may also submit a separate petition form to request a Late Add for EE 191 at 1unit, signed by Professor Brad Osgood.)
 Sign the form(s).
 Meet with an Advisor from the office of Undergraduate Advising and Research to discuss the situation and obtain the Advisor's signature.
 Submit the form to VPUE in the office of Undergraduate Advising and Research (UAR) by 5:00pm, February 7, 2014.
 "Students will not need to write a statement regarding why they wish to submit the petition. But they will need to obtain the instructor's signature, as well as the signature of a UAR Advisor. The request will be routinely approved and rather than a withdrawal with the notation of 'W,' MATH 42 or MATH 42A will be dropped from the student's record and MATH 20 (and EE 191, where appropriate) will be added.
"
 Additional details concerning switch to Math 20:

When switching to Math 20, all of your grades from Math 42 will
be deleted. You will be excused from all work from Math 20 that was
due before you enrolled in Math 20; your final grade in Math 20 will
be computed using the work turned in during the rest of the quarter.
In particular, when necessary, the weight of the first midterm will
be made up by increasing the weights of the prequizzes, homework,
second midterm, and final exam proportionally to their original
weight in Math 20. Note that Math 20 does not have a discussion
section. Please see the Math 20 course website for more details on that course, and please contact the Math 20 instructors listed there if you have additional questions.

To ensure that you can receive the signature of the Math 20 instructor in time for the UAR deadline listed above, you must email the Math 20 instructor for permission by 5:00pm on Thursday, February 6, 2014. In your email, you must include the following:
 Your full name
 The Math 20 lecture you wish to enroll in. To choose your lecture, you can visit the Math 20 course website for a
list of lectures offered, along with the lecturer contact
information. Please note that by the fifth week some of the lectures
might be full; if possible note a second choice in case your
firstchoice lecture is full and otherwise state clearly that this
is the only time slot you are able to attend. Make sure to send your
email to the instructor of your firstchoice lecture.
 Your SUNetID (for example "gocard12") and your student ID number (for example "05555555")
