Homework 1: Due Friday September 17 at 5PM
Chapter 2:
Bonus: Four spiders move in straigh lines away from a common origin on a plane in such a way that at any time they are situated on the corners of a rectangle. If three spiders move at rates of 2, 3, and 4 cm/s, find out the possible values of the speed of the fourth spider. (Due to Oscar Bolina.) Note: I haven't tried this, so I have no idea how hard it is.
