Some Math 126 practice problems and other resources:

2-dimensional tie-dye functions

Practice problems:
First set, problem: 1, 2, 3 and 4, 5 and 6, 7 and 8,
Second set, problem #: 1-3, 4-5, 6

1-D topology and equivalence by distortion

First set
Some outtakes

4D Geometry

First set (thinking about dimensions 1-4) 2011 version, Q and A about the fourth dimension
Second set (shadows of 4-D polyhedra): questions just about a 4D cube; questions about 4D prisms
More 4D and topology outtakes: set 1, set 2

The art gallery problem Practice
Weighted averages for computing grades Practice

2009 version: set 1, set 2,
Worksheet (Example sheet)

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number fractals (Julia and Mandelbrot sets): set 1, set 2, alternate set 2, link to a worksheet, links (probably outdated)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.
