Textbook and Syllabus

The course will cover roughly chapters 5-8 of the book Thomas' Calculus: Early Transcendentals, 11th edition. A detailed syllabus can be found here.

Note that regardless of what the bookstore may say, this is the only required text. Solutions manuals may be helpful, but are optional. Because MyMathLab will not be a required part of the course, you do not need to buy the "media upgrade".


Grades will be weighted as follows: 10% for homework (submitted via WeBWorK), 20% for each in-class exam, and 50% for the final exam.

Cheating will be taken extremely seriously. The minimum punishment will be an F on the exam or assignment in question, and all cases will be referred to Student Judicial Affairs.

Grading will be on a soft curve, meaning that I do not predetermine either what scores correspond to what grades, or what percentage of students get what grades. Rather, after grading each exam I will assign grade ranges using the following general criterion: those who earn an A should demonstrate a strong mastery of nearly all the material; a B should correspond to a good working knowledge of a strong majority of the material; and C should correspond to an ability to solve routine problems in a majority of the topics covered. Under this system, if you all do well, you will all get good grades.

Your lowest homework score will be dropped when calculating your grade.


Homework will be assigned once a week using the free online homework system WeBWorK. It will be given out each Monday, covering roughly the material that will be taught that week, and will be due on Wednesday the following week.

To get started with WeBWorK, go to the WeBWorK web page, log in with your UC Davis MailID (note that this is not necessarily the same as your login name), and use your student ID number as your initial password. After you log in, you should change your password using the "Password/Email" link on the left. You can then view homework assignments by going to "Homework Sets", also on the left.

Important: You are responsible for checking the assignments on the WeBWorK page every week. The first assignment is due Wednesday, January 13. In the first week of class there will also be an optional, not-for-credit, assignment covering material from 21A to help familiarize you with the WeBWork system.

Also important: You have limited attempts on problems, and typos will be counted as failed attempts, so be sure to use the "Preview" button before each time you submit an answer. You can "Email instructor" if you run into problems with the interface.


There will be two in-class exams and a final exam. These will be closed-book exams, with no calculators or notes allowed. Please bring your ID card to the exams.

Makeup exams will not be offered. If you have an unavoidable conflict with an exam date, or an emergency of some sort, you must let us know as early as possible in order to make appropriate arrangements.

Exam dates
First exam: Wed., Jan. 27
Second exam: Wed., Feb. 24
Final exam: Thu., Mar. 18, 6:00-8:00 PM

The grades for the first exam will be posted prior to the drop deadline of Feb. 1. The precise material to be covered in each of the mid-term exams will be announced as the quarter unfolds. For the first exam, the likely scope would include section 4.8 and all of chapter 5 in the textbook. For the final exam, all the material will be covered but there will be an emphasis on material taught after the second exam.


Calculators are optional for this class, and are not allowed on any exams.

Students with disabilities

Any student with a documented disability (e.g. physical, learning, psychiatric, vision, hearing, etc.) who needs to arrange reasonable accommodations must contact the Student Disability Center (SDC). Faculty are authorized to provide only the accommodations requested by the SDC. If you have any questions, please contact the SDC at (530)752-3184 or

Tutoring and other resources

You are strongly encouraged to take full advantage of faculty and T.A. office hours. In addition to these, there are various other resources available.

LSC: The LSC (Learning Skills Center) has math drop-in hours at which you can receive tutoring for Math 21B.

Math Cafe: The Math Cafe is an informal math group which meets every Tuesday evening. Although the focus is on female students, everyone is welcome to attend.

Each other: You are very much encouraged to study together. This is an easy way to make your study habits more effective.
