Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle' and μέτρον (métron) 'measure') [1] 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 ...

Trigonometry, the branch of mathematics concerned with specific functions of angles. There are six functions commonly used in trigonometry: sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). Learn more about trigonometry in this article.
Trigonometry Trigonometry (named based on a Greek word that loosely translates to "measurement of triangles") is a branch of mathematics that studies the relationships between the sides and angles of triangles. Trigonometry has many practical applications and is used in astronomy, surveying, navigation, and more. Trigonometric functions The relationships between the sides and angles of ...
The study of angles and of the angular relationships of planar and three-dimensional figures is known as trigonometry. The trigonometric functions (also called the circular functions) comprising trigonometry are the cosecant cscx, cosine cosx, cotangent cotx, secant secx, sine sinx, and tangent tanx. The inverses of these functions are denoted csc^(-1)x, cos^(-1)x, cot^(-1)x, sec^(-1)x, sin ...
