COORDINATES: Lectures meet Tues/Thur. 2:003:15 in MSB 403. The registrar calls this Sec 003, #26935
PREREQUISITES: Math 116 or Math 121
TEXT: David C. Lay, Linear Algebra And Its Applications, 3rd ed. AddisonWesley.
WEB RESOURCES: The homepage for this course is http://www.math.uconn.edu/~troby/Math227F05/. It will include a copy of the syllabus and list of homework assignments. I will keep this updated throughout the quarter.
This course will have a WebCT homepage (once I figure out how to get that setup), with discussion forums that I strongly encourage you to use. Your participation grade will be partly based on the number of useful messages you contribute. Go to WebCT at http://webct.uconn.edu/. For help with WebCT go to http://irc.uconn.edu/Student_WebCT_HELP.htm .
GRADING: Your grade will be based on two midterm exams, a final exam, quizzes, and participation.
The breakdown of points is:
Midterm 1  Midterm 2  Final  Quizzes  Participation


20%  20%  30%  20%  10% 
EXAMS: All exams are culumulative, though the second midterm will focus on material from the second part of the course. The exam dates are already scheduled, so please mark your calendars now. No makeups will be given; instead if you have an approved reason for missing an exam, the final will count for the appropriately higher percentage.
QUIZZES: Quizzes will be scheduled pseudorandomly, but will always cover problems similar to those on recent homework. Your lowest two quiz scores will be dropped.
LEARNING GOALS: Learn to work with both the computational and abstract aspects of linear algebra including:
LEARNING: The only way to learn mathematics is by doing it! Complete each assignment to the best of your ability, and get help when you are confused. Come to class prepared with questions. Don't hesitate to seek help from other students. Sometimes the point of view of someone who has just figured something out can be the most helpful.
DISABILITIES If you have a documented disability and wish to discuss academic accommodations, or if you would need assistance in the event of an emergency, please contact me as soon as possible.
HOMEWORK: Homework will be given for each section of the book, and should be done by the next class meeting. You can ask questions about the homework in one of the WebCT forums. Except for routine computations, you should always give reasons to support your work and explain what you're doing. I will not generally collect homework, but may occasionally just to check that it's being done.
You may find some homework problems to be challenging, leading you
to spend lots of time working on them and sometimes get frustrated.
This is natural. I encourage you to work with other people in person
and using blackboard. It's OK to get significant help from any
resource, but in the end, please write your own solution in your own
words.

I will host a review session on Sunday 11 December 2005, to be held in our usual room, MSB403, unless it's already occupied. In which case we'll move elsewhere, and I'll post a sign.
