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.

@AlexeiBoulbitch. This code does exactly what it promises on my system, which is V9.0.1 running on OS X 10.6.8. Just don't wrap your list of cells with Column.

Your question, as currently posed without any Mathematica code, comes across as a mathematics question, not a Mathematica question. Please reformulate it.
