In Indian astronomy, the study of trigonometric functions flourished in the Gupta period, especially due to Aryabhata (sixth century AD), who discovered the sine function, cosine function, and versine function. When during the Middle Ages, the study of trigonometry continued in Islamic mathematics, by mathematicians such as Al-Khwarizmi and Abu ...
Trigonometry in the modern sense began with the Greeks. Hipparchus (c. 190–120 bce) was the first to construct a table of values for a trigonometric function.He considered every triangle—planar or spherical—as being inscribed in a circle, so that each side becomes a chord (that is, a straight line that connects two points on a curve or surface, as shown by the inscribed triangle ABC in ...
The history of trigonometry is thus a composite of contributions from various cultures and periods, each building upon the knowledge of its predecessors. The field evolved over centuries, with different civilizations adding their insights and applications such as Ancient Greeks, Egyptians, Muslim Mathematicians and Europe and the Middle Ages.
Trigonometry traces its roots back to Ancient Babylon and Egypt. This is because the oldest surviving pieces of evidence for trigonometry are the Plimpton Tablet #322 and the Rhind Mathematical Papyrus. The Plimpton Tablet dates from around 1800 BCE and contains a table of Pythagorean triplets, or numbers that satisfy the sides of a right ...
v. t. e. 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. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
The development of trigonometry took place over several centuries and was contributed by several different mathematicians. The Egyptians and the Babylonians were the first to use ideas of trigonometric concepts at about 1500 BC ( (Massa, Romero, & Guevara, 2006). The Egyptians used ratios of similar triangles to construct their pyramids and the ...
History of Trigonometry Outline. Trigonometry is, of course, a branch of geometry, but it differs from the synthetic geometry of Euclid and the ancient Greeks by being computational in nature. For instance, Proposition I.4 of the is the angle-side-angle congruence theorem which states that a triangle is determined by any two angles and the side ...
The trigonometric functions. The use of trigonometric functions arises from the early connection between mathematics and astronomy. Early work with spherical triangles was as important as plane triangles. The first work on trigonometric functions related to chords of a circle. Given a circle of fixed radius, 60 units were often used in early ...
The history of trigonometry is intimately associated with that of astronomy, being its primary mathematical tool. Trigonometry will eventually become its own branch of mathematics, as the study of the modern trigonometric functions. Background. The people in the ancient civilizations in Egypt and Mesopotamia looked to the heavens.

The Plimpton 322 tablet. We now know that the Babylonians studied trigonometry because we have a fragment of a one of their trigonometric tables. Plimpton 322 is a broken clay tablet from the ...
Trigonometry (from Greek Τριγωνομετρία "tri = three" + "gon = angle" + "metr [y] = to measure") is a branch of mathematics that deals with triangles, particularly those plane triangles in which one angle has 90 degrees (right triangles). Trigonometry deals with relationships between the sides and the angles of triangles and with ...
Trigonometry - Angles, Triangles, Sines: In the 16th century trigonometry began to change its character from a purely geometric discipline to an algebraic-analytic subject. Two developments spurred this transformation: the rise of symbolic algebra, pioneered by the French mathematician François Viète (1540–1603), and the invention of analytic geometry by two other Frenchmen, Pierre de ...
The Beginnings of Trigonometry. Joseph Hunt History of Mathematics Rutgers, Spring 2000. The ancient Greeks transformed trigonometry into an ordered science. Astronomy was the driving force behind advancements in trigonometry. Most of the early advancements in trigonometry were in spherical trigonometry mostly because of its application to ...
Abstract. Trigonometry: A Very Short Introduction draws together the full history of trigonometry, stretching across two millennia and several cultures such as ancient Greece, medieval India, and the Islamic world. It introduces the key concepts of trigonometry, drawing readers beyond the basic relationships first encountered in school to ...
Trigonometry was not regarded as an independent branch of mathematics in the ancient period—the word itself is an early modern neologism and does not translate any ancient expression. Ancient Mesopotamian and Egyptian sources—which do not introduce angles—appear to have handled the mensuration of triangles, and slopes, through the ratios ...
The book under review is the second book in Van Brummelen’s two-part series on the history of trigonometry. The first, The Mathematics of the Heavens and the Earth: The Early History of Trigonometry , starts from the earliest times and covers ancient Greece, India, the Islamic world, and Western trigonometry up to 1550. This second book ...
François Viète (1540 - 1603, France) Can be regarded as the father of modern algebra, and as well the father of modern trigonometry. Multiple-angle formulas and trigonometric polynomials, using complex numbers. Trigonometry in complex arithmetic. Trigonometric solution of the cubic equation.
The history of sine and cosine functions is a testament to the power of mathematical concepts to transcend cultural and geographical boundaries. From their origins in ancient Indian and Greek astronomy to their formalization in the Islamic world and their integration into European mathematics, sine and cosine functions have had a profound ...
The. first thing that needs to be said about Glen Van Brummelen’s The Doctrine of Triangles: A History of Modern Trigonometry is that it’s not really a monograph. It is better described as a guided tour through the museum of mathematics. All students of mathematics know about angles, trigo-nometric functions, and their properties.
