Math 20, Spring 2019 — Schaeffer**Integral Calculus**

**Getting started!**

- The textbook for this course is Calculus by Hughesâ€“Hallett,
**7th edition**. Please ensure you have the correct edition, as problems do not have the same numbering across different editions. **Familiarize yourself with the course policies.****If you are on a Stanford University Athletics team:**Fill out the athletics survey.**If you have an accommodation from the OAE:**Please inform Dr. Schaeffer of the details by email as soon as possible.**Write down the exam dates:**Midterm 1 is on Wednesday,__April 24th__(in class); Midterm 2 is on Wednesday,__May 15th__(in class); and the Final is (almost certainly, but not yet officially) on Friday,__June 7th__(7–10 PM).*If you have a conflict with any of those dates, email Dr. Schaeffer as soon as possible. Please note that pursuant to Math Department policy, there are no alternate exam dates.*- Here are some helpful general tips for success in undergraduate math courses (h/t Adva Wolf).
**The ACE program**is a parallel 1-unit course that meets weekly (Mondays 7-9 PM in Huang 203) to discuss the content of the course and to collaborate on practice problems.

To apply click here. Applications are due Friday of Week 2 (4/12) even though the application form says otherwise.

**Prerequisites**

- The official prerequisite for this course is Math 19 or any equivalent course that covers limits and derivatives (differential calculus). Familiarity with this material will be assumed and not reviewed in class.
- The Math Department has developed an online precalculus refresher that will give you an opportunity to watch mini-lectures on precalculus topics and do many practice exercises.

We encourage you to spend some time using this resource to brush up on these topics and skills if you have concerns about your preparation. For more information, click here.

**Piazza and Gradescope**

- Piazza is where to go to ask homework questions and anything else about the course material!
- Homework in this class will be submitted and graded using Gradescope (submission guide), and your exams will be graded there as well.

This is also where your grades are recorded and where you can view your graded work. **Students officially enrolled in the course will be automatically registered with Piazza and Gradescope at the beginning of the quarter.**

**Weekly Schedule**

Regularly scheduled office hours will begin on Wednesday, April 3rd.

** SUMO (Stanford Undergrad Math Org) provides peer tutoring (and homework help) for Math 19/20/21, starting in Week 2. These sessions are drop-in, just like office hours, though tutors are not official course staff.

If you cannot make any of these times, you should ask your question on the Piazza site! Additionally, VPTL provides free individual and drop-in tutoring for the Math 19/20/21 sequence (drop-in tutoring is available Sunday–Thursday evenings). See

**Homework**

- Homework in Math 20 is submitted online using Gradescope.
- Here's a guide on how to submit assignments.
- You may also view your graded work and all recorded grades on Gradescope. (These will not be recorded on Canvas.)

- Assignments are
__due at 10 AM on Friday__every week except on exam weeks (Weeks 4 and 8) and on the first Friday of the quarter.*Please give yourself enough time to submit, and try to upload your submission at least 30 minutes before the deadline just to be sure.* - Late homework is accepted up to one day after the deadline with penalties at instructor discretion—see the course policies for details. No exceptions are made.
- Your lowest score on HWs 1–7 is dropped.
