I get what they’re trying to get at, where a mathematical theory can have proofs in multiple domains, but doing so with trigonometry isn’t a novel concept (it’s regularly done in Trig/pre-calc books, their teacher just might not have covered that or the book they used didn’t provide it). Here’s a trig based proof from 4+ years ago:

From 12 years ago:

People thinking that it hasn’t been “proven” are just r-slurred and can’t even read the extract. The commonly used proofs are algebraic or geometric, but the trigonometric proof still isn’t a new discovery.

That's proving trig identities using the Pythagorean theorem. The girls apparently proved the Pythagorean theorem with trig. You are a very dumb person who doesn't understand math and can't read.

Bruh they referenced the same trig functions in their abstract as the basis for their discovery

You don’t understand math. These videos illustrate the trivial observation that those trig identities are equivalent to the Pythagorean theorem, which is why they are called the Pythagorean identities. A proof that does not use the Pythagorean identities could actually be interesting.

A little difficult for me to determine what math they’re using since there’s only an abstract and no peer review yet, but how much do you want to be that it’s anything different than a rehash of what is in the videos?

Oh....

Then why does the story matter?

first video they prove the opposite of what you say. Haven't bothered watching the second

You can watch it backwards, proofs are reversible
