$$\int (cabin)^{-1} = ???$$

:rofl:

hahaha, funny answer.. oh.. almost forgot the plus C. Oh, shouldn't it be $$\int(cabin)^{-1} dcabin?$$

It doesn't really matter. I borrowed this from Thomas Pynchon's 'Gravity's Rainbow' where he was discussing the graffiti on bathroom walls written by renegade mathematicians. :rofl: I finally got around to sharing it with some people who would get the joke!

alright, so I am retarded. What exactly is the joke? I think I get the punchline, but I just can't seem to put everything together so that it makes sense.

The answer is $ln(wood)$ or something cheesy like that.

Probably log cabin.

### narblecinder

Perhaps I am thinking of this as a "real" joke where one needs both a setup that makes sense and a punchline.

the answer is of course ln(cabin)+C which is "the natural log cabin plus C(sea?/see?)". What I do not get is the question "the indefinate integral of cabin to the negative first" or "the indefinate integral of one over cabin".

What I am asking is if there is suppose to be a certain way to read the equation so that it makes more sense.

I think you're overanalyzing it narble. It's a quick easy funny joke. I always though x^-1 = 1/x anyways...

Either way, post some more out of the book please!!

### whozum

$$cabin^{-1} = \frac{1}{cabin}$$

### T@P

this is a similar type of math joke, but it has nothing to do with integrals.

Q: what happens when you try to cross a fly with a mountain climber?

hint: its amazingly corny

Hint on T@P's joke: You'll never, ever get it.

fly mountain climber sin theta

### Jimmy Snyder

$$\int(cabin)^{-1} dcabin = log \ cabin + C = houseboat$$

### BicycleTree

:rofl: That's great!

### t!m

Something about a scalar? Thats my best guess for the mountain climber one.

16. May 2, 2005

### BicycleTree

Yeah, something about a scalar. You'll never get it though.

### Jimmy Snyder

t!m, thanks for the hint.

Taken from the OED:
vector 3. a. Med. and Biol. A person, animal, or plant
which carries a pathogenic agent and acts as a potential source
of infection for members of another species.

You can't cross a vector with a scaler (scalar)
