Homework

There are two types of homework assignments in this course, online homework (which will be graded) and pen-and-paper textbook homework (which will not be graded).

Online Homework (required)

Online homework will be done using WebAssign. Log into WebAssign using your UC San Diego email address. (The first time you log in, you will be asked to make a Cengage account, or to link to an existing Cengage account.) You do not need a "Class Key". You will be added to the WebAssign class by your instructor or course coordinator on the first day of classes. (If you enrolled after the first day of classes, it might take a day or two before you make it into the system.)

Access Codes:  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. 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 it does not work automatically, you may need to contact Customer Support.

Loggin In:  If you are enrolled in a Math 20A course for Fall Quarter 2019, you will be automatically registered for a Canvas course called WebAssign for MATH 20A - All Sections [FA19] with subtitle MATH20A WebAssign [FA19]. (It may take a few days for you to be entered into the system.)

  • Log into Canvas at https://canvas.ucsd.edu.
  • Select the course WebAssign for MATH 20A - All Sections [FA19].
  • Under WebAssign Assignments, click on WebAssign - Math 20A.
  • You should now be logged into the WebAssign course Math 20A, section ABCD.

The first time you log in to WebAssign, you may be asked to create a Cengage account, or to link your WebAssign account to a preexisting Cengage account, if you already have one. (Cengage is the company that owns WebAssign.) For more information, consult the WebAssign help files.

Trouble Loggin In:  If you have trouble logging into WebAssign, contact WebAssign Student Support.

Note:  Your instructor may be listed as Adam Bowers (A Bowers-Coord) in WebAssign. This is because Prof. Bowers is the Math 20A Course Coordinator this term, and the same WebAssign is being used by all Math 20A instructors this quarter.

Due Dates:  Online homework due dates are subject to change based on variations in course schedule or technological issues. All online homework assignments are due at 11:00 P.M., unless specified otherwise. Log into WebAssign to see the official due dates.

  • Homework 10:   5.3, 5.4, 5.5   (Due Fri, Dec 6 at 11:00 pm)

*Homework 1 is not due until Week 2 to allow for delays in getting access to WebAssign. However, you are strongly encouraged to have Homework 1 done by Thursday, October 3, in order to keep pace with the class.

Late Submissions:  It is possible to request an automatic extension of the due date, but only for 1 day. (You may request an extension on any and all assignments.) 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.

Note:  Homework may not be submitted after the last day of classes (the Friday of Week 10).

Homework Score:  There are 10 homework assignments, each worth a total of 30 points. This means there are 300 points possible in total. However, the maximum homework score is 270 points. This means that you don't have to do all of the problems in order to get 100%. Any score 270 or better will earn a score of 100%. (It's like dropping one assignment, but the dropped problems don't have to all come from the same assignment.)


Textbook Homework (suggested)

The textbook exercises are not required, but you are encouraged to work through them. There are many exercises included in this list. It is recommended that you work through as many as you can / are able. Working through exercises is a good way to become proficient and develop understanding. Also, exam questions are sometimes based on textbook exercises, so understanding the solutions to these problems should help you perform better on the exams.

Homework 0
  • Section 1.4:   1 - 27 odd, 31, 45
  • Section 1.5:   1 - 19 odd, 23, 29, 33, 35, 37, 39, 45
  • Section 1.6:   1 - 43 odd

Notes: This should be review, so we will not cover these topics during lecture. You are advised to carefully read the sections to make sure you understand the topics very well, because they will appear again and again throughout the course. Mathematics builds on previous concepts, so without a good understanding of these sections, you will struggle with the remainder of the course. (Homework 0 does not appear in the online homework. This assignment is review and will not be graded.)
