The point value of question #3 on WebAssignment 3.1 (Part B) has been reset to zero. The reason is that two students in the class have run into a weird version of this problem. For 95% of you, your version of this problem is completely normal and is easily solved. You can use this problem as a practice problem if you like, but if you happen to run into weird things in the problem just skip it. (The weird versions of the problem are solvable, but methods from Section 3.2 are required. We'll skip that for now.)
