    This one's been around a while, but it's still fun to watch and could be the basis of some interesting "project based learning."

  • The Golden Ratio in Quartic Polynomials I believe this to be an original result. The line containing the points of inflection of any 4-th degree polynomial intersects the polynomial in two other points whose coordinates are related to the points of inflection by the golden ratio and its conjugate. This version of this idea appeared on the NCTM's On-Math site in the Winter 2004- 2005 column. Alexander Bogomolny expanded on this idea; his discussion is here.
  • The Golden Ratio in Cubic Polynomials   Once again the Golden Ratio makes an unexpected appearance, this time in cubic polynomials. The problem and its proof are in this article. Audrey Weeks, author of Calculus in Motion, has prepared a Geometers' Sketchpad animation of the proof and result which can be downloaded here.
