Material added since the beginning of class will be in purple
This class will have three in-class exams.
Answers should be explained. Proofs should be clearly arranged and rigorously explained.
The correct answer will be worth 1 point. The rest of the credit comes from correctly explaining how the answer is found.
It is best to circle your answer.
If it is not made sufficiently clear which expression is intended to be your answer
(based solely on my judgement) the answer worth the least credit will be taken as your designated answer.
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.
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, document, or file is not acceptable.
If you have any questions while I'm not around, you may e-mail me at
firstname.lastname@example.org 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 and launched Maple at the beginning of class.
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.
There will be three in-class exams worth 16% each.
- 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, come and see me.
The final exam will be worth 32%.
Homework and Quizzes will be worth 20%.
