Trigonometry - Wikipedia
Trigonometry 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. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest-known tables of values for trigonometric ratios such as sine. Throughout history, trigonometry has been applied in areas such as geodesy, surveying, celestial mech

Trigonometry (Functions, Table, Formulas & Examples) - BYJUS
In trigonometry, the angles can be either measured in degrees or radians. Some of the most commonly used trigonometric angles for calculations are 0°, 30°, 45°, 60° and 90°. Trigonometry is further classified into two sub-branches. The two different types of trigonometry are: Plane Trigonometry; Spherical Trigonometry

Trigonometry | Definition, Formulas, Ratios, & Identities
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). These six trigonometric functions in relation to a right triangle are displayed in the figure.

Trigonometry - Math is Fun
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.) Example: What is the sine of 35°? Using this triangle (lengths are only to one decimal place):

Trigonometry is the branch of mathematics which is basically concerned with specific functions of angles, their applications and their calculations. In mathematics, there are a total of six different types of trigonometric functions: Sine (sin), Cosine (cos), Secant (sec), Cosecant (cosec), Tangent (tan) and Cotangent (cot).

Trigonometry - Math
There are six trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent. These functions are often abbreviated as sin, cos, tan, csc, sec, and cot. Their definitions are shown below. sine: cosine: tangent: cosecant: secant: cotangent: Sine, cosine, and tangent are the three most commonly used trigonometric functions.

Trigonometry Calculator. Simple way to find sin, cos, tan, cot
Trigonometry is a branch of mathematics. The word itself comes from the Greek trigōnon (which means "triangle") and metron ("measure"). As the name suggests, trigonometry deals mostly with angles and triangles; in particular, it's defining and using the relationships and ratios between angles and sides in triangles. The primary application is thus solving triangles, specifically right triangles, but also any other type of triangle you like.

The inverse functions, on the graphing calculator, for each of the three trigonometric functions are found directly above the buttons for sine, cosine and tangent. They appear as sin-1, cos-1 and tan-1. Note: sin-1(x) is read "the angle whose sine is x". You will discover, in later courses, that there are actually many angles whose sine is x ...
