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. My main reason for joining StackExchange is to participate in Mathematica.SE. I enjoy answering question when I can, but I also enjoy working at making the site a better place to visit.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 10.0.2. 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.

Please do not post images of your work, especially when the images display at a size that make them unreadable. Please post your actual Mathematica code as text that can be copied and pasted in a Mathematica notebook. Without such, no one will be able to reproduce your problem, nor will they be able to experiment with possible repairs.

What is the error message and from what expression are you getting it? Add the answers to these questions to your question; don't answer me by posting a comment.
