Course Materials
The home page for our "Contemporary mathematics" course (Math 203) is
here.
That was the version when I last taught
the course in Fall 1997. For the version, updated to Spring 1998, see
Judy Walker's home page.

- Skydiving Mathematica notebook, project for differential equations,
Math 221: A person weighing 170 pounds jumps from an airplane, at an
altitude of 10,000 feet. There is no wind. The person is wearing a big
suit and lies "flat", resulting in a free-fall terminal velocity of 98 MPH.
At an altitude of 2500 feet, the person's parachute opens. This takes
2 seconds. The air resistance coefficient changes linearly during
this period. After opening, the terminal velocity (under canopy) is
1000 feet per minute. Determine the altitude of the skydiver at time t.
