Finding the Inverse of Cabin Function

SUMMARY
The forum discussion revolves around a humorous interpretation of the integral of the function "cabin," specifically \(\int (cabin)^{-1} dcabin\). Participants joke about the punchline being "ln(cabin) + C," referencing both mathematical concepts and literary elements from Thomas Pynchon's 'Gravity's Rainbow.' The conversation highlights the playful nature of math jokes, emphasizing the relationship between integrals and logarithmic functions, while also touching on the concept of scalars and vectors in mathematics.
PREREQUISITES- Understanding of integral calculus, specifically indefinite integrals.

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. 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.

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!

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

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

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

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)
