Hello, I'm Falcon8765. I noticed that you made a change to an article, Hyperbolic partial differential equation, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.  Falcon8765  (T ALK ) 23:48, 16 November 2014 (UTC)
