When were trigonometric functions first used?
While the early study of trigonometry can be traced to antiquity, the trigonometric functions as they are in use today were developed in the medieval period. The chord function was discovered by Hipparchus of Nicaea (180–125 BCE) and Ptolemy of Roman Egypt (90–165 CE). The functions of sine and versine (1 - cosine) can be traced back to the jyā and koti-jyā functions used in Gupta period Indian astronomy ( Aryabhatiya, Surya Siddhanta ), via translation from Sanskrit to Arabic and then from Arabic to Latin. (See Aryabhata's sine table .)

What is trigonometry?
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.

Since trigonometry is the relationship between angles and sides of a triangle, no one invented it, it would still be there even if no one knew about it! The first people to discover part of trigonometry were the Ancient Egyptians and Babylonians, but Euclid and Archemides first proved the identities, although they did it using shapes, not algebra.

Notation
Traditionally, a three letter abbreviation of their name is used as a symbol for representing trigonometric function in formulas, namely "sin", "cos", "tan", "sec", "csc", and "cot" for sine, cosine, tangent, secant, cosecant, and cotangent, respectively. (The cosecant function may instead be abbreviated to the five-letter "cosec".) Moreover, functional notation, such as sin(x), is used. Parentheses may be omitted when no confusion may occur; an example of a case requiring brac…
Right-angled triangle definitions
If the acute angle θ is given, then any right triangles that have an angle of θ are similar to each other. This means that the ratio of any two side lengths depends only on θ. Thus these six ratios define six functions of θ, which are the trigonometric functions. In the following definitions, the hypotenuse is the length of the side opposite the right angle, opposite represents the side opposite the …
Radians versus degrees
In geometric applications, the argument of a trigonometric function is generally the measure of an angle. For this purpose, any angular unit is convenient, and angles are most commonly measured in conventional units of degrees in which a right angle is 90° and a complete turn is 360° (particularly in elementary mathematics).
However, in calculus and mathematical analysis, the trigonometric functions are generally regard…
