Homework List:

The following is a running list of the assigned homework problems.  The assignments are grouped into "weekly chunks" and each Friday morning I will collect the homework due for that week.

All problems refer to the exercises in our textbook "Linear Algebra and Differential Equations," by Peterson and Sochacki, Addison-Wesley, 2002.

***Bonus and Resubmit Policy***:  

1.  I will often assign bonus problems.  If you solve a bonus problem flawlessly I will add one point to your homework grade for that week.  There will be no partial credit on bonus problems.

2.  After I return your assignment to you, you will have one week to resubmit to me any homework problems that you got wrong.  There will be no partial credit on resubmissions--all or nothing--so your work must be flawless.  If flawless, I will return half of the credit that I originally took off.  You are welcome to get help from me before resubmitting.

Happy Thanksgiving!

M - Extra Credit Assignment--Due Wednesday 12/05/2012 at beginning of class
W - Review day, no new problems.

Th - Section 4.3, #s 1, 7, 13, 23, 25
        You may want to try 23 and 25 first and check that you have the form correct in the back of the book.  Aside from the examples in Section 4.3, you can also look at the examples in Section 4.5.  These are physics applications problems, but you will see that the method being used to solve the equations is the "method of undetermined coefficients."  
F -  Review of the BIG IDEAS in the course.
