Sections 12.1 and 12.2; Due November 15

Difficult: I do not completely understand the Legrange interpolation polynomial, or why it works. It seems like it is not so important anyway, it would be a simple to solve the system that was as it would be to solve the system linearly, as far as I can tell. The rest of these sections made plenty of sense.

Reflective: Yeah, I'd love to see someone work one of these schemes into a spy movie.

--"Quick, we need to launch the nuclear warhead. Get the president, the general, and the secretary of state!"

--"Ok gentlemen, do you remember your point in three space?"

*The next ten minutes are spent setting up a matrix and solving the resulting system of equations by hand because the aliens knocked out the mainframe so only the launch computer works...during this time all of the audience leaves...Except for three kids from a college math class*. It is a neat idea though, I like the ideas on how to have multiple "secret holders" that have to be together to get the secret.
