Definitions can, however, be ambiguous or otherwise useless, e.g. the definition of "derivative" in your Wacky New Calculus, John Gabriel.

By your wacky definition, the "derivative" of such simple linear functions as y=x is undefined everywhere. It is also undefined at all points of inflection on a curve. So, it is completely useless. Deal with it, John Gabriel. Time to cut your losses and move on. Your outrageous antics here are getting you nowhere.
