This assignment is due at the beginning of class, Thursday, 10/01/09.
You must bring a copy to
class—it can be typed or neatly handwritten. If necessary, add illustrations by hand or with
computer graphics.
Late homework is not accepted.
Read the directions carefully.
For every question that asks you to “justify your answer,” a simple
calculation or response without explanation is not sufficient. Make your arguments
understandable and convincing.

Section 1.1, # 10, 14

See the following sheet.
It is probably easiest to complete (and then grade) if you print off the sheet and fill that in for
your homework.
