In the "Questions" section, I'll color the active questions green so that they are easier (in theory) to find as you scan through the page. Please let me know if I've missed anything.

Homework is due at the beginning of class on the day that it is due.
You should turn in your homework in a pile on the desk at the front of the classroom.
Homework may be turned in later but will be penalized based on just how late it is - typically

1 point off for turned in late during the class,

5% off for being turned in late the same day,

10% off per day. (weekends count for two days)
i.e. 10 days later, it's too late to get a makeup homework turned in.

When writing up homework, you should circle (or otherwise clearly indicate) your answers.

It's good to work together, but you should write/type your own homework.
Simply copying another person's work or *Maple* file will result in a 0 and a letter to the Dean of Students.

You should come to class prepared. This means that I expect you to have done the homework, brought your book to class, and silenced your cell phone.

If you have a cell phone, please make sure that it does not ring audibly during class. Phone calls should, in general, not be answered during class.
No texting during class.

- If you don't understand something,
**ASK** - If I'm going too fast,
**STOP ME**. I enjoy mathematics. When I get on a roll, I tend to keep going. -
**SHOW YOUR WORK**. The correct answer will only be worth 1 point. I want to verify that you understand the process. - If you are having problems understanding the material, see me or go to the learning center.

The final exam is 36% of the course grade. Homework, quizzes and exams constitute the other 64%.
