Math 20 is a 3 credit course in introductory calculus.
The class covers integration, applications of integration,
and an introduction to differential equations. A more
detailed breakdown of the schedule and homework can be
found at the Course Schedule
Students need to have a strong foundation in
'precalculus'. In particular, you need knowledge of
standard mathematical notation and vocabulary, comfort
with the concept of a function, a mastery of all things
concerning lines (how to compute slopes, several ways to
write the equation of lines), and an ability to manipulate
algebraic expressions (simplify fractions, factor
polynomials). Students also need to be able to compute
limits and derivatives of functions.
Lectures: Mondays, Wednesdays, and Fridays in 200-203
from 1:30pm to 2:20pm.

You are encouraged to attend any of the office hours
provided by the instructor or course assistants. No
appointment is necessary: just drop in at the scheduled
office hours with your questions!
The scheduled office hours for any given week can be
found on the Office Hours
page. Note that they might change slightly from week to
week, so it's always a good idea to check both the time
and location before walking across campus.
The textbook is Calculus: Single Variable, 6th
edition, by Hughes-Hallett, Gleason, McCallum, et
al. (This will also be the text for Math 21.)
Most homework exercises and suggested reading are taken
from the book, so you should have a copy. It is not
recommended that you use a copy of a different edition,
since the homework problems will come from the 6th edition
and the numbering may be different.
For your convenience the textbook is available for
purchase at the Stanford bookstore. However, this is a
pretty standard textbook and you might be able to buy it
elsewhere new or used for a lower price.
Your grade will be based on the following components:
- Homework: 25%
- Midterm 1: 25%
- Midterm 2: 25%
- Final Exam: 25%
There are no predetermined numerical cutoffs for letter
There will be weekly homework posted on the homework
page. Your solutions to the assigned homework will be
graded and returned to you.
Homework will be due every week on Wednesday at the start
of lecture. For details about handing in your homework,
see the homework page.
Upon enrollment in the course, all subsequent homework
assignments will count towards your homework grade. Your
lowest homework score will be dropped from your total
score at the end of the quarter.
Late homework will only be accepted under very

The exam dates are given below; it is your responsibility
to verify right now that you can attend these
exams. Please contact your instructor as soon as possible
if you will not be able to attend a midterm. If you need

If you have an academic or physical disability which
requires academic accommodations, please obtain a letter
from the Office of Accessible Education. Once you have
done so, please let the instructor know as soon as
possible so that proper accommodations can be made.
For accommodations on exams, your instructor must have
your letter from OAE no later than one week prior
to the exam. Otherwise, we may not have sufficient time to
make the accommodations.
If you are involved in a sport which may require you to
travel this quarter, and especially if you will miss
either of the midterms, please let the instructor know as
soon as possible so that appropriate accommodations can be
made. If you do not let the instructor know at least a
week in advance of a missed exam, you may be denied the
opportunity to take it at an alternate time or on the
road. You are also responsible for homework while
traveling. See the homework
for information about turning in homework.
- Extra credit
assignments: Occasionally students ask for
extra credit in order to improve their grade. While we
can recommend additional practice problems, we cannot
offer them for credit as it would be unfair to the
entire class if only a small number of students were
allowed a chance to improve their grade. If you become
worried about your understanding and grade in the
course, please see your instructor as soon as possible
- Calculator policy:
Calculators are not used in a systematic way in the Math
19-20-21 sequence. Calculators are not allowed or needed
on any of the exams. Occasionally, homework problems may
call for the use of a scientific or graphing calculator,
and it is fine to use them for this purpose.
- Honor code policy:
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
