It's not as good as Math v 2.1.2 but it gave me some good laughs. Note: I omitted two because they were images, too lazy to put them here properly.
36 Methods of Mathematical Proof
If the proof of a theorem is not immediately apparent, it may be because you are trying the wrong approach. Below are some effective methods of proof that might aim you in the right direction.
# 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 necessity: "It had better be true, or the entire structure of mathematics would crumble to the ground." # 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 lack of sufficient time: "Because of the time constraint, I'll leave the proof to you." # Proof by postponement: "The proof for this is long and arduous, so it is given to you in the appendix." # Proof by accident: "Hey, what have we here?!" # Proof by insignificance: "Who really cares anyway?" # Proof by profanity: (example omitted) # Proof by definition: "We define it to be true." # Proof by tautology: "It's true because it's true." # Proof by plagiarism: "As we see on page 289,..." # Proof by lost reference: "I know I saw it somewhere...." # Proof by calculus: "This proof requires calculus, so we'll skip it." # Proof by terror: When intimidation fails... # Proof by lack of interest: "Does anyone really want to see this?" # Proof by logic: "If it is on the problem sheet, it must be true!" # Proof by majority rule: Only to be used if general agreement is impossible. # Proof by clever variable choice: "Let A be the number such that this proof works..." # Proof by tessellation: "This proof is the same as the last." # Proof by divine word: "...And the Lord said, 'Let it be true,' and it was true." # Proof by stubbornness: "I don't care what you say it is true." # Proof by simplification: "This proof reduced to the statement 1 + 1 = 2." # Proof by hasty generalization: "Well, it works for 17, so it works for all reals." # Proof by deception: "Now everyone turn their backs..." # Proof by supplication: "Oh please, let it be true." # Proof by poor analogy: "Well, it's just like..." # Proof by avoidance: Limit of proof by postponement as it approaches infinity # Proof by design: If it's not true in today's math, invent a new system in which it is. # Proof by authority: "Well, Don Knuth says it's true, so it must be!" # Proof by intuition: "I have this gut feeling."

whoa at first i read the thread title as "36 methods of masturbation proof" and was like whoaaaa
+ Show Spoiler +vaseline between the matress and boxspring is my favorite
these always piss me off when im reading textbooks or in lecture lol:
# Proof by postponement: "The proof for this is long and arduous, so it is given to you in the appendix." # Proof by insignificance: "Who really cares anyway?" # Proof by calculus: "This proof requires calculus, so we'll skip it." # Proof by lack of interest: "Does anyone really want to see this?"

These are great, better than the math v2.1.2.

LOL! :D Some of these are quite commonly used, both in textbooks and during lectures.

# Proof by clever variable choice: "Let A be the number such that this proof works..."
I like this. 
 Their are four errors in this sentance.

Yeah, hehe, first thing I thought while reading these were that they're lecturer's best friend
Proof by obviousness, lack of sufficient time, plagiarism and tesselation are some of their favourites
I remember someone telling me that proof by calculus is a favourite in one of his economics classes

Nice one! This reminds me of the time I was in uni studying math, when we would always rip on physics students for using most of these to make stuff work the way they want them to..

I like "we define it to be true" the most. I definitely see that one a lot, only really in stats though.

# Proof by imagination: "Well, we'll pretend it's true..." # Proof by definition: "We define it to be true."
These two go together perfectly, and our calculus professor used them a lot, hahaha.

Proof by iteration: "We have tried countless scenarios and all agrees" Proof by reiteration: "If you say something seven times in a row it becomes true" Proof by proof: "According to proof A and B, C is already proven" Proof by google: "6 million hits can't be wrong" Proof by wiki: "If it isn't true today at least it will be tomorrow" Proof by ignorance: "Ignoring these facts this becomes obvious" Proof by idiocy: "With the correct choice of logic everything can be proven"
