By using the Law of Sines, and avoiding the Pythagorean theorem’s trig identity (sin²α + cos²α = 1), Johnson and Jackson successfully proved the theorem without resorting to circular reasoning.

Trigonometric identities are powerful tools for simplifying complex equations in math and science. Three core ...

Both girls created different, but similar, proofs that disproved the accepted thinking that since trigonometry (the study of triangles) is itself based on the Pythagorean Theorem, any theory that ...

Using a trigonometry rule called the Law of Sines, the students showed that the "proof is independent of the Pythagorean trig identity sin2x + cos2x = 1." In their published paper, ...

Two high school students have proved the Pythagorean theorem in a way that one early 20th-century mathematician thought was impossible: using trigonometry. Calcea Johnson and Ne’Kiya Jackson ...

NEW ORLEANS – Two students at a school in New Orleans have presented evidence of a mathematical discovery that scholars have been trying to prove for 2,000 years.School officials at St. Mary’s ...
