For Thursday, September 10: Section 5.4 #1,2,3,7,11,15,23,27,37. Turn in these exercises on Friday.

There will be a Quiz at the beginnning of class Thursday. You may use

For Friday, September 11: Section 5.4 #10,20,33,38,39,42; Section 5.5 #1,5.

Turn in the Section 5.4 homework exercises discussed Thursday.

Turn in the Section 5.5 homework exercises.

We will have a quiz covering through Section 5.4.

The hitting-a-spring-mass-with-a-hammer worksheet is available online.

Check your ANGEL mail for any corrections to the summaries that you turned in at the end of class Thursday.

Turn in the problems on the worksheet.

There will be a quiz on systems of differential equations on Monday. Use of

Turn in the Section 9.3 homework.

We will be covering

- LaPlace Transforms
- Systems of First order Differential Equations
- Approximations

This class will have three in-class exams - most likely during the 3rd, 6th or 7th, and 9th weeks.

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.

There may be two other types of quizzes given in class: announced and unannounced.

A stapler is probably a good investment for most of you. Multi-page homeworks should be stapled together, not mutilated.

Homework will typically be due at the beginning of class on the due date. Homework may be turned in later but will be penalized based on just how late it is - typically 10% off per day. 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. If the homework is on a worksheet that is passed out to the class, you will generally be expected to write your answers on a separate sheet of paper, in a well-organized fashion. Answers should be written on the worksheet only if answer blanks have been specifically provided.

If you have any questions while I'm not around, you may e-mail me at 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 and launched

- 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.

Write-ups should be neatly presented. Write-ups returned on the information sheet handed out to the groups will not be accepted. Write-ups handed in at the end of class may be hand-written. Write-ups for work outside of class should be typed.

The final exam will be worth 36%

Quizzes and homework will be worth 10%
