trigonométrie

Also known as trig

branche des mathématiques qui étudie les relations entre distances et les angles dans les triangles et les surfaces sphériques

AI overview

Trigonometry is a branch of mathematics that studies the relationships between the angles and side lengths of triangles, particularly using trigonometric functions that connect a right triangle's angles to ratios of its sides. The field developed in the Hellenistic world over 2,000 years ago out of a need to solve problems in astronomy, and it became foundational enough that mathematicians across cultures—from ancient Greece to India—developed various tools and tables to work with it.

La trigonométrie (du grec τρίγωνος / trígonos, « triangulaire », et μέτρον / métron, « mesure ») est une branche des mathématiques qui traite des relations entre distances et angles dans les triangles et des fonctions trigonométriques telles que sinus, cosinus, tangente.
