goniometrie

Also known as trig

Trigonometry () is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest-known tables of values for trigonometric ratios (also called trigonometric functions) such as sine.

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.

Goniometrie, trigonometrie (Oudgrieks: τρεῖς (treis), drie, γωνία (gōnia), hoek en μετρεῖν (metrein), meten) of driehoeksmeetkunde is een tak van de wiskunde die zich bezighoudt met driehoeken en in het bijzonder de oorspronkelijk op driehoeken gebaseerde goniometrische functies zoals sinus (sin), cosinus (cos) en tangens (tan). Dit is een basisvak van de vlakke meetkunde, omdat alle andere vormen die door rechte lijnen worden ingesloten, opgebouwd kunnen worden uit driehoeken. De goniometrie kent vele toepassingen, onder andere bij de driehoeksmeting.
