Trigonometry  Wikipedia
Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and side lengths of triangles.
Introduction to Trigonometry  Math is Fun
The main functions in trigonometry are Sine, Cosine and Tangent. They are simply one side of a rightangled triangle divided by another. For any angle "θ": (Sine, Cosine and Tangent are often abbreviated to sin, cos and tan.)

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  Math.net
Trigonometric functions are functions related to an angle. There are six trigonometric functions: sine, cosine, tangent and their reciprocals cosecant, secant, and cotangent, respectively. Sine, cosine, and tangent are the most widely used trigonometric functions. Their reciprocals, though used, are less common in modern mathematics.
Trigonometry  What is Trigonometry? Formulas, Table, Examples  Cuemath
Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a rightangled triangle with its angles. The ratios used to study this relationship are called trigonometric ratios, namely, sine, cosine, tangent, cotangent, secant, cosecant.
