Homework

Homework problems will come in two forms: Practice Problems and Due Problems. Generally, the Practice Problems will come from the textbook, while I will write the Due Problems myself, (although there may be exceptions in both cases). Only the Due Problems actually need to be handed in. You don't have to turn in the Practice Problems, but you should try them! If you find them easy, then you can skip to the next batch, but the Practice Problems will usually help you with the Due Problems. In any case, you'll need to practise the material if you want to remember it for quizzes or exams, a subsequent course, or the rest of your life.

As you do your homework, I encourage you to talk with your fellow students. In my class, this is not cheating! However, the final result that you turn in to me should be your own work, written by you in your own words; you should understand (at least more or less) what you've written. Don't turn in anything that you copied from another person, and don't have other students copy from what you plan to turn in. You can also look at other books and talk to other people, but the same rules apply as if those books or people were your fellow students: Understand what you turn in, and write your answers in your own words.

In case you miss the homework, you can download it here; see the downloading help if you have trouble. When I return each homework assignment, I'll post my solutions here too; once that happens, I won't accept it late unless you arrange something with me ahead of time.
