Course Description and Prerequisites

Math 20 is a 3 credit course in introductory calculus, second in the Math 19-20-21 sequence. The class provides an introduction to single variable integration, including many integration techniques and applications to geometry. We will also explore differential equations and parametric equations. A one-page summary of the important information from this webpage can be found here, and a more detailed breakdown of the schedule and homework can be found at the Course Schedule page.

Students are expected to have a strong foundation in precalculus, such as comfort with the concept of functions, equations of lines, trig and inverse trig, ability to manipulate algebraic expressions, factoring polynomials, etc. Further, students are expected to be familiar with the material of Math 19. In particular, students should be comfortable with the idea of a limit, the idea of the derivative, and taking derivatives of a wide range of functions. Further, students should know (and know when to apply) the product rule and chain rule. Students who are unsure of their background should see their instructor as early as possible. Students who want to brush up on their precalculus skills can find more resources on this page.

Office Hours

You are encouraged to attend the office hours provided by any of the instructors or course assistants, regardless of which lecture you are enrolled in. 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 all the way across campus.

Textbook

The textbook for this course is Calculus: Single Variable, 6th edition, by Hughes-Hallett, Gleason, McCallum, et al. (This was the textbook for Math 19 and will be the text for Math 21.) This course mainly focus on topics from chapters 5, 6, 7, 8, and 11.

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.

Grades

Your grade will be based on the following components:

  • Homework: 15%
  • Midterm Exam 1: 25%
  • Midterm Exam 2: 25%
  • Final Exam: 35%

There are no predetermined numerical cutoffs for letter grades.

Homework

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 9am. 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. If you enroll by January 18, you are elligible to have your lowest homework score dropped from your total score at the end of the quarter. To qualify for this, you must complete the assignment at this link by 5pm on January 18.

Late homework will be accepted only under very exceptional circumstances.

Exams

There will be two EVENING midterm exams and a university scheduled final exam. Most of the problems on the exams will be similar to the problems in the weekly homework, but there will always one or two harder problems. The material covered by each exam is given by the suggested reading and homework, including the practice problems.

All exams for Math 20 this quarter are closed-book, closed-notes, with no calculators or other electronic aids permitted. Individual exams will be neither curved nor scaled.

The evening midterm dates are given below; it is your responsibility to verify right now to you can attend these exams. Please contact your instructor as soon as possible if you will not be able to attend one of the midterms. In any case, if you need to reschedule the exam you must do so no later than two weeks before the exam. The final exam cannot be rescheduled, per department policy.

You will have assigned seating for exams. The seating chart will be posted in the exam classroom on the day of the exam; you are responsible for arriving a few minutes early to find your seat before the exam starts. Failure to sit in your assigned seat will be considered a breach of the Stanford Honor Code and be handled accordingly.

If an emergency occurs and you need to miss an exam, contact your instructor as soon as possible.

  • Midterm 1: Wednesday, February 1, 8:00pm - 9:30pm
  • Midterm 2: Wednesday, February 22, 8:00pm - 9:30pm
  • Final exam: Monday, March 20, 7:00pm - 10:00pm

Office of Accessible Education accommodations

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.

Student Athletes

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 informationa about turning in homework.

Other important policies

  • 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 for advice.
  • 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 NP.
