I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in the classical Greek synthetic form and in the more modern analytical form.

Perhaps as a newcomer to Mathematica, you will find it useful to learn that Part[x[[2]], 2] is more concisely expressed as x[[2, 2]]

comment How to get better quality EPS graphics
Once again I ask you to take the time to format your code properly. And that includes not dumping it into the editor as one long line that requires readers to do a lot of scrolling,
