Note. There are four (4) problems in each homework set. Math 6441 students need to do
all 4 problems while Math 4441 students need to do any three (3) problems out the four.
If a Math 4441 student submits all 4 problems, then one of the lowest score(s) is dropped.
There is a bonus point for a Math 4441 student doing all 4 problems correctly.
There are three (3) PDF files for the homework sets and exams, one with the problems
only, one with hints, and one with solutions. Links are available below.
