Some Math 126 practice problems and other resources:

2-dimensional tie-dye functions | Notes |

1-D topology and equivalence by distortion | |

4D Geometry | First set (thinking about dimensions 1-4) 2011 version, Q and A about the fourth dimension |

The art gallery problem | Practice |

Weighted averages for computing grades | Practice |

Chaos | |

Fibonacci numbers | A page with links to most things A Fibonacci assignment Just Fibonacci NIM, more NIM type questions, still more Spirals and golden ratios Fibonacci problems using the subscript notation |

Fractals | Self similar fractions: set 1, variation on set 1, * Fractal dimension (self similar) practice, variation, another variation Complex number fractals (Julia and Mandelbrot sets): set 1, set 2, alternate set 2, link to a worksheet, links (probably outdated) *Note: I only have about 5 good self similar fractals I can ask questions about on quizzes, so I'm kind of careful about what I put in the practice problems pages. There are lots of self similar fractals out there, but most of them are hard to figure out. |

Infinity | set 1; set 2; set 3 |
