Hello, I'm Satellizer. I wanted to let you know that I undid one or more of your recent contributions to Cartesian coordinate system because it didn't appear constructive. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page.  ~ satellizer ~ ~ talk ~  06:05, 14 February 2013 (UTC)
