Chromatic number and non-simple cycles @Nick: Not every graph with odd cycles is 3-chromatic. Every graph with odd cycles requires at least 3 colors, but 3 might not be enough. The chromatic number can be arbitrarily large. |

Graph Problems(Euler,Hamilton,Color) There is a well-known criterion for when graphs are Eulerian. It should be easy to apply here. For Hamiltonian and 4-coloring, try some examples and you'll figure it out. |

Expectancy value for the percentage of points lying in the Convex Hull (3D) I would expect the percentage to go to zero as $n$ grows. (It is sort of like the ratio of surface area to volume.) |

Is there a set-theoretic definition of Projective Space? No problem. The more people there are thinking about projective space, the better! |

Can we make $\tan(x)$ arbitrarily close to an integer when $x\in \mathbb{Z}$? Let me know when your son is ready to apply for college! :) |
