Online Homework

Online homework will be done using WebAssign. WebAssign can be accessed from within TritonEd under "Tools".
If you enrolled after the first day of classes, it might take a day or two before you make it into the system.

NOTES
• To get an access code for WebAssign, you can either (1) purchase the textbook from the UCSD Bookstore, which comes bundled with a multi-term WebAssign access code, or (2) purchase ELECTRONIC ONLY access from the WebAssign website (after first logging in through TritonEd).
• If you already have a multi-term access code (because you took Math 20A last quarter, for example) then you may use the same code. If you were using a different username, then you must link your accounts. You can do this by clicking on "My Options" (in the upper right) and then selecting the "Accounts" tab.

Syllabus Quiz: The Syllabus Quiz can be found in WebAssign. It has 10 question, each one multiple choice or True/False. You have one attempt per question. The quiz is "open syllabus," so you may have the syllabus open when you take the quiz. The Syllabus Quiz is due on the Friday of Week 2 and will be counted towards your homework grade.

Late Submissions: It is possible to request an automatic extension of the due date (of 7 days); however, there are penalties for late submissions. Late submissions earn a maximum of 50% of their total score. This penalty applies only to exercises submitted after the due date and not to those already submitted before the due date.

Homework may not be submitted after the day of the Final Exam.


Textbook Homework

These assignments will not be turned in and will be not graded; however, certain exam questions are based on textbook homework problems, so understanding the solutions to these problems should help you perform better on the exams.
(Also, if you seek help from the instructor or TAs, they may do these problems instead of the online problems.)

This list is subject to revision during the term. Please check regularly for updates. (Last updated 11 Jan 2017)

Note:  Online homework due dates are subject to change based on variations in course schedule or technological issues. Official homework due dates are listed in the online homework system.

Homework Zero (Review)     (No due date; textbook exercises only)
  • Section 5.2:   7, 9, 13, 14, 15, 16, 23, 43, 44, 45, 46, 47, 55, 56, 57, 58, 65, 71
  • Section 5.3:   3, 7, 25, 27, 37, 45, 49, 55, 69, 71
  • Section 5.4:   4, 9, 21, 23, 25, 33, 37, 43, 47, 55, 59
  • Section 5.5:   5, 17, 23, 28, 29, 33, 39, 40, 41

Reading: Sections 5.2-5.5. These sections were covered in Math 20A, and consequently this is review. Mathematics builds on previous concepts, and without a good understanding of these sections, you will struggle with the remainder of the course.

Homework 1     (Online HW due Thu, Jan 19)
  • Section 5.6:  7, 11
  • Section 5.7:  15, 19, 25, 27, 33, 41, 51, 71, 76, 77, 87, 91, 101, 102, 103, 104
      Challenge Problems: 42, 73

Reading: Sections 5.6-5.7. Note that there are many exercises for Section 5.7. Substitution is one of the most basic and most useful methods available for evaluating integrals. It is important that you become well-versed in its use and a good way to do that is by doing as many exercises as possible.

Homework 2     (Online HW due Thu, Jan 26)
  • Section 6.1:  1, 3, 9, 17, 19, 21, 33, 41, 43, 53
  • Section 6.2:  6, 7, 9, 11, 13, 15, 17, 43, 49
      Note: Skip "Density" and "Flow Rate" (pp. 343-345)
  • Section 6.3:  9, 13, 15, 19, 25, 27, 31, 45, 49

Reading: Sections 6.1-6.3. You may skip "Density" and "Flow Rate " in Section 6.2.

Homework 3     (Online HW due Thu, Feb 2—Note: Day of Exam 1)
  • Section 7.1:  9, 11, 13, 15, 21, 23, 25, 35, 45, 49, 51
      Challenge Problems: 77, 89
  • Section 11.3:  7, 8, 9, 10, 13, 15, 17, 19, 29, 37, 39, 41
  • Section 11.4:  5, 7, 8, 9, 10, 13, 14, 15, 16, 19, 20
      Note: Skip "Arc Length" (p. 606)

Reading: Sections 11.3-11.4 and Section 7.1. The topic of Section 7.1 ("Integration by Parts") is the "other basic method" for evaluating integrals. Make sure you are comfortable using it, because you will see it again and again in your mathematics courses.
