Text: Differential Equations and Linear Algebra by C. H. Edwards and D. E.
Penney
Coverage: We will be covering material from Chapters 1,2,3,5, and 6. The
material may not be covered in a linear order, but I will try to make the
material understandable.
Class Grade: Your numerical grade will be determined by the following
parts of the course listed below. Your letter grade will then be based on a
scale very close to the 90-80-70-60 scale. Plus (+) grades are often given as
a reward for doing better on the final than your numerical score would
indicate (e.g. your numerical score is 73 but your final exam score was 85%
- probably your letter grade would be C+).
Please feel free to email me questions at any time. I check my email often
so getting an email response will usually be quick.
I. Daily Homework (10 %). You will be assigned a few problems to be
turned in each day. These are to be turned in at the beginning of the class –
put them on a neat pile at the front of the classroom. In the upper right hand
corner of the first page, put your box number, your name, and the
assignment number in this order and vertically. If all three pieces of
information are not there and there is not a proper staple, the grader will not
look at your paper. Your numerical score for this part will be MIN{(Your
Total / (.95*Total))*10,10}, where Total is the total number of points.
Notice that this computation will allow you to miss a couple homeworks and
not be penalized.
ABSOLUTELY NO LATE HOMEWORK ACCEPTED.
DON’T EVEN ASK!!
If you are unable to attend class for some reason, you must make
arrangements to have someone turn in your homework.
II. Quizzes (10%). The quizzes may be announced, unannounced, with
Maple, or without Maple. Indeed, there may be short quizzes over the
assigned reading, or there may be take-home (even group) quizzes. Your
numerical score for this part will be MIN{(Q/(0.95*Total))*10,10}, where Q
is your total quiz score and Total is the total number of quiz points.
No Make Up for Quizzes
If you have a legitimate excuse for missing a quiz, your quiz grade will be
determined by your final exam percentage.
III. Differential Equations Proficiency Quiz (5%). At some point during
the quarter, you will have 3 opportunities to solve a few differential
equations -- no partial credit and your final score will be 0 or 5.
IV. In Class Exams (50%).
Exam 1 – Friday, Sept. 29
Exam 2 – Tuesday, Oct. 24
Each exam will be worth 25%.
No Make Up for Exams
If you have a legitimate excuse for missing an exam, your exam grade will
be determined by your final exam percentage.
V. Final Exam (25%)
Attendance: I expect you to be in class. My attendance policy is the same
as the school’s official policy – see Page 3 of RHIT’s Academic Rules and
Procedures.
Classroom Etiquette:
1) Questions are encouraged. Please feel free to ask questions at any time
of the class period. Ask about what is taking place, what you read the
previous night, … ask, ask, ask!!
2) Everyone should be respectful of everyone else.
3) Please do not annoy me or others during the class period by reading the
thorn, finishing a paper for another class, talking continuously, playing
games on your laptop etc etc
4) Indeed, the use of the laptop must be related to this class (e.g. working
on the worksheet of the day or a quiz…). Violating this policy (e.g.
using mail or the web or …) could result in lowering your class grade or
being removed from my class roster. I will certainly send a letter to your
academic advisor and the dean. I will simply not put up with anyone
using the computer when an explanation is taking place or when someone
is answering a question. You should not be connected to the network
unless I specifically tell the class to connect. Downloading files for a
particular class period should be done before coming to class. You will
be able to see the instructions at our web site.
5) Sometimes the homework for the next day (or days) may be posted early
in the week. You are not allowed to work on homework problems during
the class period. Homework problems are to done “at home”.
6) Always willing to add to the list….
