You can see how Mathematica handles your example of the involute of the circle at the MathWorld site: http://mathworld.wolfram.com/CircleInvolute.html where you can download a Mathematica notebook containing code for the involute, and a free viewer to display the code and the plots. Wolfram's free viewer, called Mathematica Player, runs on Ubuntu and other operating systems. There is a prettier version of the involute packaged as a live demo that runs on Mathematica Player at: http://demonstrations.wolfram.com/CircleInvolute/ which shows another way to share functions. You need a full version of Mathematica to create these demos, but anyone can view and manipulate them for free. In my not so humble opinion, Mathematica is far and away the best product in the market for working with advanced mathematics. Some people may squawk at its price (unless you are a student), or dislike being tied to commercial code, but it will take a while for the open source community to catch up to Stephen Wolfram and company. To share your involute gear function with another Mathematica user you would email them or post on a web site something like the following line of text. d = 1; ParametricPlot[{d (Cos[t] + t Sin[t]), d (-t Cos[t] + Sin[t])}, {t, 0, 2 Pi}] PS. I use Mathematica for CAD (for R&D, not production work), and program it to generate g-code for EMC2 directly, or have it write out text files of coordinates and import these into Catia or Pro/E, when they run out of steam.
