Trigonometry - Wikipedia
Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships between side lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

Trigonometry (Table, Formulas and Solved Examples)
Trigonometry is one of those divisions in mathematics that helps in finding the angles and missing sides of a triangle with the help of trigonometric ratios. The angles are either measured in radians or degrees. The commonly used trigonometry angles are 0 °, 30 °, 45 °, 60 ° and 90 °.

Trigonometry
The main functions in trigonometry are Sine, Cosine and Tangent They are simply one side of a right-angled triangle divided by another. For any angle " θ ": (Sine, Cosine and Tangent are often abbreviated to sin, cos and tan.)

Trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

Trigonometry, as the name might suggest, is all about triangles. More specifically, trigonometry is about right-angled triangles, where one of the internal angles is 90°. Trigonometry is a system that helps us to work out missing or unknown side lengths or angles in a triangle.

What is trigonometry? Trigonometry is the study of the relationships within a triangle. For right angled triangles, the ratio between any two sides is always the same, and are given as the trigonometry ratios, cos, sin, and tan. Trigonometry can also help find some missing triangular information, e.g., the sine rule.

The period of a function is the number, T, such that f (q+T)=f(q). So, if w is a fixed number and q is any angle we have the following periods. (wq) = 2 p T wsin cos(wq) 2 p T = w (wq) = p T wtan
