Math21b, Fall 2007, Linear Algebra and Differential Equations

Homework is due at the beginning of class. No late homework will be accepted.
Collaborations are welcome however you must turn in your own copy and list on it the names of your collaborators.
Use words to explain your work, if necessary. Show your work.
A star * after a problem indicates that the problem is recommended only. You do not turn it in, nor will it be graded.
For the final grade, in the computation of the average of the homework scores, the lowest three homework scores will be dropped. A zero score given for a missed or late homework paper will count as one of the three lowest homework scores.
