Logistics for handing in homework

The homework is due on Wednesdays at 10am. Homework submissions will be handled electronically via the Gradescope platform. Students registered for the course at the end of the first weekend should receive an email to sign up for Gradescope. Otherwise, please contact your instructor starting the morning of October 1.

Gradescope accepts only electronic submissions, so you will need to scan your homework before uploading it. Make sure to allot plenty of time to follow the submission instructions here before each deadline.

Assignments will be posted no later than a week before they are due. Any change to a posted assignment will be announced in class and via email.

For the written assignments

Be sure to show your work (helps with partial credit and lets us comment on your process).

Remember: calculators are not allowed for the exams and homework is one way to help prepare yourself for the tests. Therefore, you should avoid using a calculator when completing your homework. However, there are some homework problems that we feel are important for building conceptual understanding and yet need a calculator. Such problems are indicated below with a superscript "T".

Practice problems

Along with each assignment, there is also a list of "Practice Problems." These are not to be turned in but are strongly encouraged. You cannot succeed in this class without doing the practice problems. Given the large number of practice problems, you might want to look at some each week while completing the homework and save others for refreshing the material throughout the quarter/exam studying.

Most of these practice problems are odd numbers, meaning you can check your work by looking at the answers in the back of your textbook. Practice problems that are even numbered at great to discuss with your peers and/or in office hours.

Solutions to the homework assignments will be posted here within a week after the due date.
