Trigonometri

Also known as trig

läran om samband mellan vinklar och sidor i en triangel

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.

Trigonometri är läran om samband mellan vinklar och sidor i en triangel. Trigonometrin har sina största praktiska, direkta tillämpningar inom lantmäteri och navigation där den används för triangulering, men används också inom ett flertal områden inom matematiken, bland annat geometri och komplex analys och därmed även inom fysiken.
