Relaxing at home and got nerd sniped again via YouTube. Looked interesting enough to give it a shot though the thumbnail was more than a bit misleading as they used `n` instead of `x` which has certain connotations associated with it.

Früher hieß es, der Beweis ist trivial oder so. Das ist eine schöne Steigerung. 😉

Yay, got nerd sniped with another math problem. I made it a smidge more difficult than it should've been, but I'm happy that I got the correct answer eventually.
The problem: Given `1 / tan(x) = tan(1 / x)`, solve for `x`.

Say you have a machine that spits out hundreds of very long solution attempts to the Riemann hypothesis. Each is tedious and hard and then humans start reading it all until they refute most and finally find one that is correct. It’s a gigantic effort for the humans, but now they have a proof.
Did the machine then _solve_ the Riemann hypothesis?

Nerd sniped myself this time: after getting sniped yesterday with showing that for primes `p >= 5` that `24 | p^2 - 1`, I decided to look at primes `p, q` where `p, q >= 5` and see if `24 | p^2 - q^2`.
#math #nerdsnipe

Given primes p and q where both p and q are greater-than-or-equal-to 5, prove that 24 divides p squared - q squared.

If Gauß had had an electronic calculator, would he have proved better and more theorems or weaker and fewer?
It would have spared him days and days of rote calculation but maybe this calculation was prerequisite for insight?

OK, but the results are still just paper links, not what the LLM thinks about them. So the only thing that changed is that it is much much slower now?
Maybe the LLM just formulates a query to the old scholar? Too many layers of "oh how can we build an LLM into this"...
OK, nobody in #math uses Google Scholar like this anyway. We only use it look at publication records of people and do reverse citation search (which papers cite this one I have).
