Impossible? Not for Them! Calcea Johnson and Ne’Kiya Jackson, two high school students from New Orleans, astonished mathematicians by proving the Pythagorean theorem using trigonometry. Many mathematicians thought a trigonometric proof of this foundational theorem of geometry was not possible without using circular reasoning. Jackson and Johnson, however, created one. The Pythagorean theorem, a cornerstone… Continue reading A Trigonometry Proof of the Pythagorean Theorem?
