Homework Assignments

Updated 12/5/23

Note: There are two components to each homework assignment: graded and recommended, and both should be completed by the due date.

The graded part of each assignment should be submitted to Gradescope by the indicated deadline.
- To log in to Gradescope, use the Gradescope link in the menu bar at left of the main page of your Math 20E Canvas site. To submit your assignment, follow the link to the appropriate assignment and carry out the instructions. Detailed help for using Gradescope can be found at https://help.gradescope.com/.
- Before being uploaded, assignments should be in a single pdf file. See Gradescope's Submitting an Assignment page for more complete instructions.
- Please make sure your files are legible before submitting. Unreadable solutions will not earn credit.
- For those who might be interested, a link to the LaTeX source of each assignment is included. If you don't know what that is, you may safely ignore it.

The recommended part of each assignment will consist of selected exercises from your textbook and is not to be submitted for a grade; however, exam and quiz questions may be based on recommended exercises and you are strongly encouraged to complete the recommended exercises. Remember: The main reason for doing exercises is not for the small amount of credit you will earn; rather, it is for the deeper understanding you will attain by doing the exercises.
