Here you'll find postings about homework, exams, and anything else that becomes relevant during the quarter.
New! Solutions for the final practice problems are available here, and Homework 9 is still available here.
Classes are on Monday, Wednesday, and Friday, 8:30am--9:20am, in 246 MEB (Mechanical Engineering Building).
C-417 Padelford Hall: Monday and Tuesday, 1--2pm.
We will use Elementary Linear Algebra, 6th ed., by Larson and Falvo.
Homework will be assigned via WebAssign. Here's a quick introduction to how to use it.
In general, assignments will be due on Wednesday mornings, but check the schedule below as the quarter progresses.

Practice Midterm 1 is available as this PDF. Solutions are here.
Solutions to Midterm 1 are available here.
Practice Midterm 2 is available as this PDF. Solutions are here.
Solutions to Midterm 2 are available here.
Final practice problems are available here.
| Small Midterm: | 10% |
| Big Midterm: | 4% |
| Final Exam: | 36% |
| Homework: | 40% + 10% |
Also, the homework component will be computed out of a total of 90%. This means that if there are a total of 100 points, and you score 72, your homework grade is 72/90 = 80%. (I'm doing this instead of dropping a lowest homework.)
Due to the snow disruption of the "Big Midterm", grades have been redistributed. The above "90%" calculation of the homework grade applies only to the WebAssign homework. (The final assignment could be considered as a take-home component of the exam.)
