Logistics for handing in homework

Assignments will be posted no later than 6 days before they are due. Any change to a posted assignment will be announced in class and via e-mail. Homework is to be handed in at the beginning of lecture every Wednesday at the start of your lecture.

Your lowest homework grade will be dropped.

For the written assignments

Be sure to show your work! (This 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".

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

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. It will be challenging to succeed in this class without doing some extra 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 numbered, meaning you can check your work by looking at the answers in the back of your textbook.
