I'm interested in writing another tutorial on some math topic. I'm curious, is there anything people would be particularly interested in? I'm especially interested in something that doesn't already exist--say a programmer's approach to some math problem. There are a zillion topics that would fit the bill. I suppose I could list a few:

* Counting things, and coding it
* Calculating sin(x) from scratch
* A survey of calculus
* Numerical integration
* Basic probability
* Polynomials and You
* Basic real analysis
* Trig functions in code
* Modular arithmetic
* Theoretical CS Logic

Thanks for any responses .
