## Math 20B Homework

### Updated 11/11/16

We will have two different kinds of homework assignments in this class: *online homework* (which will be graded) and "paper-and-pen" *textbook homework* (which will not be graded).

## Online Homework

### Online homework (graded) will be done using WebAssign via TritonEd. Use the *Access Webassign* link, which will be visible in the main menu column or under *Content*.

- No homework assignment scores will be dropped at the end of the quarter.
- Late Homework: It is possible to request an automatic extension of the due date (of 3 days within 7 days of the deadline) through Webassign. However, late submissions earn a maximum of 50% of their total score. This penalty applies only to excercises submitted after the due date and not to those already submitted before the due date.
- Note: Homework may not be submitted after Wednesday, December 7 (the day of the final exam).

## Textbook Homework

### These assignments will not be turned in and will be not graded; however, exam questions are often 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.
