Answers should be explained. The correct answer will be worth 1 point. The rest of the credit comes from correctly explaining how the answer is found. The words "used Maple" are not an explanation and will result in a loss of 1 point. Similar evasions will also result in a loss of credit.
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 is not acceptable.

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.
