Trigonometric identities are powerful tools for simplifying complex equations in math and science. Three core groups—reciprocal, quotient, and Pythagorean—form the foundation.

This article was originally published with the title “A Simple Rule for Certain Trigonometric Identities” in SA Supplements Vol. 75 No. 1950supp (May 1913), p. 315 doi:10.1038 ...

Trigonometry class has tripped up generations of teenagers, yet none of its puzzles spark more head‑scratching than the classic right‑triangle riddle. The formula a² + b² = c² looks tidy on the ...

An ancient theory may no longer be set in stone. Two American teenagers have challenged centuries-old math conventions by developing new trigonometric proofs for the Pythagorean theorem, stirring ...

Popular Mechanics said they used the Law of Sines while avoiding the Pythagorean theorem’s trigonometric identity (sin²α + cos²α = 1).

Ne’Kiya Jackson and Calcea Johnson of Louisiana published a new study proving the Pythagorean theorem using trigonometry, a feat mathematicians long thought could not be done ...

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." ...
