Celebrating Women's History Month
In 2022, U.S. high school students Calcea Johnson and Ne'Kiya Jackson astonished teachers when they discovered a new way to prove Pythagoras' theorem using trigonometry after entering a competition at their local high school. As a result, both students were awarded keys to the city of New Orleans, and even received personal praise from Michelle Obama.
Many mathematicians over the years have proved the theorem using algebra and geometry. Yet proving it using trigonometry was long thought impossible, as the fundamental formulae of trigonometry are based upon the assumption that the Pythagorean Theorem is true—an example of circular reasoning.
Nevertheless, both Johnson and Jackson managed to solve the math problem independently of each other and prove Pythagoras' theory without resorting to circular reasoning—a feat that has only been managed twice previously by professional mathematicians.
Their paper detailing their discoveries was published in the journal American Mathematical Monthly.
