HOMEWORK
Math 203 - Fall 2001
There will usually be 1 or 2 problems in each assignment which are more
challenging than the others. Don't panic! Being able to do all parts of all
homework problems is not expected. By all means ask us for help;
struggling through hard problems is a good way to learn the material. But not
all such problems are equally important.
