Two high school seniors have presented their proof of the Pythagorean theorem using trigonometry — which mathematicians thought to be impossible — at an American Mathematical Society meeting.

In a new peer-reviewed study, Ne'Kiya Jackson and Calcea Johnson outlined 10 ways to solve the Pythagorean theorem using trigonometry, including a proof they discovered in high school.

Calcea Johnson and Ne'Kiya Jackson presented their new findings on the Pythagorean theorem to the American Mathematical Society last week.

In their new book, Hidden Harmonies, husband and wife mathematics team Robert and Ellen Kaplan pay tribute to that familiar formula you learned in high school math class.
