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.
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.)

Sine, Cosine and Tangent  Math is Fun
Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a RightAngled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle: "Opposite" is opposite to the angle θ. "Adjacent" is adjacent to (next to) the angle θ. "Hypotenuse" is the long one.

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.
