Trigonometry  Wikipedia
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.

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 concerns the description of angles and their related sides, particularly in triangles. While of great use in both Euclidean and analytic geometry, the domain of the trigonometric functions can also be extended to all real and complex numbers, where they become useful in differential equations and complex analysis.
Trigonometry  from Wolfram MathWorld
The study of angles and of the angular relationships of planar and threedimensional 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.

Trigonometry: FAQ (article)  Trigonometry  Khan Academy
Trigonometry is the study of triangles and the angles and sides that make them. We can use trigonometry to find missing information about triangles, such as how long a side is, or how big an angle is. We can also use trigonometry to model patterns that repeat, such as waves, cycles, and rotations.
