Course Policy
Material added since the beginning of class will be in purple
This class will have four in-class exams - most likely during the 3rd, 5th, 7th and 9th weeks.
Note: I don't set grades using a 93/86/77/70 "straight scale" system. I plan to challenge you to excel. This means that the exam averages will generally be lower than what you are used to.
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, e.g.,
"Set f'(x)=0, solve for x".
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.
There will be two parts to the final exam.
For the first part, you will be allowed the use of only a writing utensil.
For the second part, you may use clean Maple worksheets and a writing utensil.
The weights for the grade are given below.
There may be two 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.
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.
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.
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,
irrelevant information about other topics is written on the 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 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.
- 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.
I will assign some `group' projects in this class.
Groups will consist of either three or four members. Write-ups from smaller or larger groups will not be accepted unless prior approval has been given.
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. Maple code may be included as part of an appendix or in figures, but should not be considered as a `formal' write-up. Similarly, `scratch-work' is unacceptable. Neatly written partial results may be turned in, but scribbles will reduce your grade.
The following errors are taboo. If you make them, do not expect any credit on the problem
- Volume and area must be positive
- If your computation produces a area or volume that is negative or complex, you cannot simply erase the negative sign or imaginary part. You must set up the problem correctly
- a vector cannot be equal to a scalar
- a differential cannot be equal to a non-differential
- an equation has an =, and expressions on both sides of the =.
- Limits on an integral cannot depend on the variable being integrated
- Limits on an iterated integral cannot depend on interior variables
- When evaluating an integral for which you already know the value, if you've set up an incorrect integral and pretend to evaluate the integral by simply copying the known value, rather than evaluating the integral and commenting on the difference, you should not expect any credit.
The basic "by hands" skills:
- Basic arithemtic
- Algebra: manipulation of terms, solutions to quadratic equations and systems of linear equations, manipulation of exponentials and logarithms
- Geometry: knowledge of area and volume rules for simple shapes;
triangles, parallelograms, trapezoids, circles, cubes, spheres, pyramids
- Trigonometry: maipulation and evaluation of trigonometric functions and their inverses
- Vector arithmetic, including evaluation of dot products and determing the angle between two vectors
- Deriviatives: partial derivatives of the elementary functions
- Integration: evaluation of iterated integrals of elementary functions
The elementary functions are:
polynomials, trigonmetric functions and their inverses, exponential functions, and logartihms.
A summary of the grade weights
There will be four in-class exams worth 15% each
The final exam will be worth 30%
Quizzes and homework will be worth 10%
Extra credit that is earned will be added on to your grade after the curve has been determined.
