A challenge problem (contemporaneous with Assignment 3)

Describe a method for the following: given a truth table column, give a logical expression, using only logical operations we've defined—"and," "or," "not," "implies"—that yields the given truth table column.

For a concrete example, say that there are three variables, and that we'd like the truth table column to end up as FFTFFFTT.

(What, you may ask, is a challenge problem? Something that's maybe a little too interesting for the homework or an exam, but relevant to our work and maybe even fun. No bonus points given, no solutions posted—but do tell me if you've made some progress on one of them.)

Opening handouts, with links

You might need a syllabus, or a copy of Assignment 1, or a copy of the sheet of mathematical curiosities that we discussed.

Here's another version of one of the "proofs" we discussed, with links to further discussion and other fallacies. (You might also be interested in the OED's discussion of the number of words in the English language.)

Graders and Tutors Needed

The Department of Mathematics employs a limited number of students to assist in correcting homework and tutoring students. The courses for which graders and tutors are sought range across the whole mathematics curriculum but most particularly students are needed to help with calculus and statistics courses. These positions are a good opportunity to solidify one's knowledge of the subject while also earning some money. New graders are paid $6.60/hr, while experienced graders are paid $6.90/hr. New tutors earn $7.10/hr and experienced tutors are paid $7.40/hr.
