Now now, that just won't do. That doesn't constitute a complete proof. Here are some more acceptable methods for proving propositions:Proof by Obviousness:
"The proof is so clear that it need not be mentioned."Proof by General Agreement:
"All in favor?..."Proof by Imagination:
"Well, we'll pretend it's true."Proof by Convenience:
"It would be very nice if it were true, so..."Proof by Plausibility:
"It sounds good so it must be true."Proof by Intimidation:
"Don't be stupid, of course it's true."Proof by Mumbo-Jumbo:
"For any epsilon > 0 there exists a
corresponding delta > 0 s.t. f(x)-L < epsilon
whenever x-a < delta."
... and so on. Alas, I didn't come up with those methods though: for a complete list, see http://www.pen.k12.va.us/Div/Winchester/jhhs/math/humor/proof.html
