Please refrain from making unconstructive edits to Wikipedia, as you did with this edit to the page Calculus. Such edits constitute vandalism and are reverted. Please do not continue to make unconstructive edits to pages; use the sandbox for testing. Thank you.  Thatguyflint  undefined 17:36, 30 November 2009 (UTC)
