Homework Information:

Warning: When this book (and hence webassign) write "log(x)", they mean the natural logarithm, ln(x). In modern math, it is more common to use this convention.

This class will have two different types of homework assignments: online homework, and book homework.

Online homework through Webassign:

• Online homework will be handled through Webassign. Webassign homework assignments will count towards 20% of your final grade. You can access Webassign through your TritonEd account. To do so, log into TritonEd, and access our class page. Click the link titled "tools" on the navigation bar on the right hand side of the page. You will find the Webassign link on this page. Your Webassign account has already been created for you.

• You will need a webassign access code in order to access the homework assignments. The access code comes included with the book if you buy the book from the UCSD bookstore. Otherwise you can purchase an access code online. If you are on the waitlist, or if you are unsure if you are staying in the class, you can choose to use the free 14 day trial. If you eventually purchase the access code, your work will automatically transfer over.

• The Webassign homework will be due by 11:59pm each Saturday night. The first assignment is due January 20th.

• Please be careful when entering your response, and be sure to follow Webassign's answer formatting guidelines. You can submit up to 10 responses to each question, and your most recent response will count towards your grade.

• Late homework will not be accepted, and no homework assignment will be dropped from your final grade.

Pen and paper homework assignments from the book:

• You will also have homework assignments from the exercises in the book.

• Book homework assignments will not be collected and will not count towards your final grade. However, the book assignments are mandatory, and you will be expected to have completed them.

• You can find the book homework assignments posted at the bottom of this page

• Many of the assigned book problems are similar to the online homework.

• I will post solutions to the book assignemnts on this webpage.

Reading assignments:

• In addition to your problem sets. It is also expected that you will read the sections in the book corresponding to the material covered in class. Pease see the course calendar for specifics.
