Please refrain from making unconstructive edits to Wikipedia, as you did at Cartesian coordinate system. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism may result in the loss of editing privileges. Do not attempt to disguise vandalism like that, it does not fool us at all.
