Math 20

  Fall 2017

Course Information

Course overview

Course Description: The definite integral, Riemann sums, antiderivatives, the Fundamental Theorem of Calculus, and the Mean Value Theorem for integrals. Integration by substitution and by parts. Area between curves, and volume by slices, washers, and shells. Initial-value problems, exponential and logistic models, direction fields, and parametric curves.

Prerequisites: Math 19 or equivalent.

Course Website:
Grades will be made available through Gradescope.

Textbook: Hughes–Hallett, Calculus (Single Variable), 6th Edition

Office Hours: Office hours are posted on the Course Timetable. Students from any section are welcome and encouraged to attend any of Michail, Jenny, or Dylan's office hours.

Homework: Assignments will be posted to the Homework page of the course website. Solutions should be uploaded to Gradescope by 9am on Fridays. Late homework is generally not accepted, except under extenuating circumstances. Your homework solutions should be neat and legible. You may work in groups and discuss homework problems with other students, but your solutions must be written up independently and in your own words. Each student's lowest homework score will be dropped. A detailed homework policy is given below.

Exams: Our class will write two midterms this quarter, on the Wednesday evenings of Weeks 4 and 7. Each test will cover approximately three weeks of material. The final exam will cover material from the entire quarter. All exams are closed-book. If you must miss an exam, please give us as much notice as possible. See below for information on exam conflicts and accommodations.

Placement diagnostic and enrolment: If you have not previously taken a calculus course at Stanford then you must take the math placement diagnostic by noon on 12 October in order to register for Math 20. Upon taking the test, you will receive an email with your recommended placement, and a second email once the prerequisite has been lifted from your account to allow you to enroll in math courses. If you have questions please email calcplacement "at"

Grade Assignment: There is no predetermined correspondence between numerical scores and letter grades, and grades are not fit to any target distribution. Your instructors will decide at the end of the quarter how your scores translate into letters, taking into account factors such as the length and difficulty level of the exams. If you have any questions about your standing in the course, we would be happy to speak with you in office hours or by appointment.

Redress of Grades: If you believe that one of your assignments or exams was graded incorrectly, or that a grade has been incorrectly recorded, please fill out this grade redress form. Grades must be appealed within three days of the release of the results.

Exam conflicts and accommodations

Students who know they will miss an exam or are otherwise in need of an accommodation must contact their lecturer (Michail or Jenny) as soon as possible, and at least one week before the exam, and provide any necessary documentation. Make-up exams are only offered under very specific circumstances and must be arranged in advance.

Athletics and university-sponsored activities: Students may be permitted to reschedule an exam that conflicts with an athletic event or certain other Stanford activities. If you are involved with a university-sponsored activity that may create a conflict, let us know by filling out this form. Student-athletes who will be away from campus during an exam must have the exam administered on the exam date by athletic staff. Please ensure that your lecturer is in touch with the appropriate staff member at least one week before the exam.

Religious observances: Contact your lecturer (Michail or Jenny) right away if you have a conflict between an exam and a religious observance.

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 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.

Illness or emergency: If unforeseen circumstances (such as a medical problem or family emergency) prevent you from writing a midterm at the scheduled time, contact Jenny or Michail as soon as possible to discuss the options. In some situations you may be asked for documentation. Options may include dropping a midterm or taking a grade of incomplete.

Homework policy

Late homework policies: Late homeworks are generally not accepted, except possibly under extenuating circumstances such as prolonged or recurrent illness. Students who have scheduled activities such as athletics or religious observances that conflict with the homework due date are expected plan accordingly to submit their assignments before the deadline.

Dropped assignment: To accommodate unexpected minor problems such as short-term illness, each student's lowest homework score will be dropped.

If you experience a severe or long-term issue that interferes with your coursework, contact your lecturer (Michail or Jenny) as soon as possible.

Collaboration and outside sources: You are welcome to use other texts and online resources to review the mathematical theory and computational techniques we cover. You may not, however, seek out solutions to specific homework problems. Any use of our textbook's solution manual is absolutely unacceptable. Outside sources should be used to improve your understanding of the material, not as a shortcut to finish assignments with an incomplete understanding. Use your discretion.

You are encouraged to discuss the homework with classmates and work on difficult problems in groups. You must, however, write your solutions independently, and you are responsible for understanding what you've written. If you have worked on your homework with a group, you are expected to write your solutions on your own and without referring to notes or other material that came out of the group discussion.

The homework is your foremost resource for practice with the course material, and for feedback on your work. Doing the homework thoughtfully is essential to your success in this class. Since the homework is weighted lightly (15%), there is very little to gain in submitting solutions you do not understand.

The grader will be alert to assignments copied from other students or from the solution manual. Such solutions will receive no credit, and instances of academic dishonesty will be reported. Stanford students have high standards for academic integrity, and we expect this class will be able to take advantage of study groups and other resources to improve, not undermine, your learning in the course.

Honour Code: The Stanford Honour Code is available through Stanford's Office of Community Standards.

Affordability of course materials

Stanford University and its instructors are committed to ensuring that all courses are financially accessible to all students. If you are an undergraduate who needs assistance with the cost of course textbooks, supplies, materials and/or fees, you are welcome to approach your instructor directly. If would prefer not to approach your instructor directly, please note that you can ask the Diversity & First-Gen Office for assistance by completing their questionnaire on course textbooks & supplies or by contacting Joseph Brown, the Associate Director of the Diversity and First-Gen Office (jlbrown "at"; Old Union Room 207). Dr. Brown is available to connect you with resources and support while ensuring your privacy.
