Thanks for your recent edit on the Calculus/Functions page. It's always good to have more people helping with the book. I don't mean to discourage you, but I undid the revision you made to that page. Although your revision is more concise than the old one, there is a loss of some important information such as the discussion about independent and dependent variables. Feel free to re-work your revision to include the missing material. Again, thanks for contributing to the project! Greenbreen (discuss • contribs) 02:50, 7 April 2011 (UTC)
