Two students who discovered a seemingly impossible proof to the Pythagorean theorem in 2022 have wowed the math community again with nine completely new solutions to the problem.
While still in high school, Ne'Kiya Jackson and Calcea Johnson from Louisiana used trigonometry to prove the 2,000-year-old Pythagorean theorem, which states that the sum of the squares of a right triangle's two shorter sides are equal to the square of the triangle's longest side (the hypotenuse). Mathematicians had long thought that using trigonometry to prove the theorem was unworkable, given that the fundamental formulas for trigonometry are based on the assumption that the theorem is true.
Jackson and Johnson came up with their "impossible" proof in answer to a bonus question in a school math contest. They presented their work at an American Mathematical Society meeting in 2023, but the proof hadn't been thoroughly scrutinized at that point. Now, a new paper published Monday (Oct. 28) in the journal American Mathematical Monthlyshows their solution held up to peer review. Not only that, but the two students also outlined nine more proofs to the Pythagorean theorem using trigonometry.
I'm not a mathologist, so this reads to me like "they proved it is what it is because of the way it is. That's pretty neat!"
I can understand it's significant, but that's about it. From my understanding, this doesn't really change anything about math, it's just something we didn't think was possible being proven possible.
Please correct me, mathletes! Hilariously almost all my fields of interest require math... cries in physics
Before these young ladies came up with these proofs, the only way people could come up with to balance the equation was to use things that boiled down to the actual thing they were trying to prove. It's like saying all things are made of atoms, but then people say well what the heck are atoms made of, smartypants?! So these girls found the Higgs-Boson of trigonometry while in high school as a piece of extra credit on a test. That's my understanding as a low B, high C math student.
Edit: For any of you that are mathy, here is their actual paper.
From the Conclusion of the paper:
Huh. Reading that paper, I understand. Throw out the nonsensical and focus on the actual and the solutions are right there. Interesting.
You know, I'm still not "mathy"... But it made way more sense just reading the actual paper than it did reading summaries, explanations, or the article.
Thanks, Chief.
