Three of our faculty gave talks.

Mr. W. Conway Link gave three talks:

• (#7) Functions - They're Not Just for Polynomials Anymore

  Examples of other interesting and useful functions include random variables, bar coding, and encryption functions. Also results of 3 year survey on ability of post-college algebra students to recall definition of functions and to apply the definition.

• (#42) The Mathematics of the Enigma Cipher Machine

  Several counting principles are used to enumerate the exact number of theoretical key settings and machine configurations for the WWII era German Enigma Cipher Machine. A Swiss Cipher Machine (CA 1944) will beon display.

• (#60) Numbers in the News: Examples of Misuse and Abuse of Numbers, Graphs, and Tables in the Media

  A sobering, but humorous look at examples of graphs, tables, and numbers in the print media.

Dr. Julien Doucet gave a talk on two separate occasions:

• (#29, #120) Reducing Trigonometric Equations by Using Spokes on a Carousel

  A simple technique (using spokes on a carousel) for students to reduce trig functions of the form
  ±sin(±q+n 90^°), ±cos(±q+n 90^°), etc. will be discussed

Dr. Carlos Spaht, II, gave a talk:

• (#24) LaPREP: An Enrichment Program in Math and Science that is Working Louisiana Preparatory Program (LaPREP) is an enrichment program for high-ability middle school students in the mathematical sciences that is held on the LSUS campus. Participants attend seven weeks of intellectually demanding classes and seminars for two consecutive summers. Eighty percent of its participants have been minority students and over 60% have been female. The program is highly acclaimed, winning local, regional and national awards. In the session, LaPREP and its success will be discussed.

Dr. Judith Covington attended as the NCTM representative for LATM.

Mr. Rogers Martin also attended the conference.
