### Course Policy

Whenever you are asked for a probability, the probability must be at least 0, and at most 1. If your answer does not lie in [0,1], you will receive no credit for the problem.

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. When you use Maple, you must explain what you've done mathematically.
The final exam will be given during finals week. If you are making arrangements for travel home, you should make sure that they will not conflict with the final exam schedule. If your parents will be purchasing airline tickets for you, you should contact them and remind them not to schedule you on a flight that might cause you fail a class.
The weights for the grade are given below.
A stapler is probably a good investment for most of you. Multi-page homeworks should be stapled together, not mutilated.
Place your name and Campus Mailbox number in the upper right-hand corner of your homework. 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.
The grader and I reserve the right to return as unacceptable any homework that is inadequately prepared. (full of scratch work, problems out of order, submitted on crumpled or fringed paper)
If you have any questions while I'm not around, you may e-mail me at john.rickert@rose-hulman.edu and I will reply as soon as I can.

You should come to class prepared. This means that I expect you to have done the homework, brought your book to class, silenced your cell phone, and be prepared with questions about material that you don't understand.
If you bring your 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 are found facebooking or texting uring class you may be penalized by a reduction in your course grade.
• 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 as soon as possible.

There will be 3 in-class exams each worth 15%.
The final exam will be worth 30%.
Quizzes and Homework will be worth 25%.
There may be two types of quizzes -- announced and unannounced.
