Hey I have been reading a lot about chaos equations and the like recently. I found interesting analog chaos computers and have seen some chaos equations that can be fed an input such as an oscillator or audio stream and output a very interesting and complex output.

Anyway I am a little lacking in the differential calculus skills and I am having troubles inputting equations with t) type things into an fexpr~ or expr~. I did see the lorenz attractor example in the help for expr~, but if someone could help me figure out how to get from a differential equation to an expr~ or fexpr~ that calculates it that would be awesome. Or maybe I just need to get some calculus books.

the page below has some examples of the types of equations I am talking about.
