Hello, I'm Arthur Rubin. I wanted to let you know that I undid one or more of your recent contributions to Trigonometry 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. Thanks! — Arthur Rubin (talk) 20:25, 16 December 2012 (UTC)
