He was also a pioneer in spherical trigonometry. For the second one, the text states: If we want the sine of the sum, we add the products, if we want the sine of the difference, we take their difference".

He also discovered the law of sines for spherical trigonometry: Also in the late 10th and early 11th centuries AD, the Egyptian astronomer Ibn Yunus performed many careful trigonometric calculations and demonstrated the following trigonometric identity: Al-Jayyani — of al-Andalus wrote The book of unknown arcs of a sphere , which is considered "the first treatise on spherical trigonometry ".

The method of triangulation was first developed by Muslim mathematicians, who applied it to practical uses such as surveying [42] and Islamic geography , as described by Abu Rayhan Biruni in the early 11th century.

Biruni himself introduced triangulation techniques to measure the size of the Earth and the distances between various places. In , Levi ben Gershon, known as Gersonides , wrote On Sines, Chords and Arcs , in particular proving the sine law for plane triangles and giving five-figure sine tables. A simplified trigonometric table, the " toleta de marteloio ", was used by sailors in the Mediterranean Sea during the 14thth Centuries to calculate navigation courses.

Regiomontanus was perhaps the first mathematician in Europe to treat trigonometry as a distinct mathematical discipline, [49] in his De triangulis omnimodis written in , as well as his later Tabulae directionum which included the tangent function, unnamed. The Opus palatinum de triangulis of Georg Joachim Rheticus , a student of Copernicus , was probably the first in Europe to define trigonometric functions directly in terms of right triangles instead of circles, with tables for all six trigonometric functions; this work was finished by Rheticus' student Valentin Otho in In the 17th century, Isaac Newton and James Stirling developed the general Newton—Stirling interpolation formula for trigonometric functions.

Euler used the near-modern abbreviations sin. Prior to this, Roger Cotes had computed the derivative of sine in his Harmonia Mensurarum The works of James Gregory in the 17th century and Colin Maclaurin in the 18th century were also very influential in the development of trigonometric series. From Wikipedia, the free encyclopedia.

In the Arabic language there is also the word jaib meaning "bay" or "inlet". When Robert of Chester came to translate the technical word jiba, he seems to have confused this with the word jaib perhaps because vowels were omitted ; hence, he used the word sinus, the Latin word for "bay" or "inlet".

A History of Mathematics.

It should be recalled that form the days of Hipparchus until modern times there were no such things as trigonometric ratios. The Greeks, and after them the Hindus and the Arabs, used trigonometric lines. These at first took the form, as we have seen, of chords in a circle, and it became incumbent upon Ptolemy to associate numerical values or approximations with the chords.

A cycle of the seasons of roughly days could readily be made to correspond to the system of zodiacal signs and decans by subdividing each sign into thirty parts and each decan into ten parts. Our common system of angle measure may stem from this correspondence. Moreover since the Babylonian position system for fractions was so obviously superior to the Egyptians unit fractions and the Greek common fractions, it was natural for Ptolemy to subdivide his degrees into sixty partes minutae primae , each of these latter into sixty partes minutae secundae , and so on.

It is from the Latin phrases that translators used in this connection that our words "minute" and "second" have been derived. It undoubtedly was the sexagesimal system that led Ptolemy to subdivide the diameter of his trigonometric circle into parts; each of these he further subdivided into sixty minutes and each minute of length sixty seconds.

Trigonometry, like other branches of mathematics, was not the work of any one man, or nation. Theorems on ratios of the sides of similar triangles had been known to, and used by, the ancient Egyptians and Babylonians. In view of the pre-Hellenic lack of the concept of angle measure, such a study might better be called "trilaterometry", or the measure of three sided polygons trilaterals , than "trigonometry", the measure of parts of a triangle. With the Greeks we first find a systematic study of relationships between angles or arcs in a circle and the lengths of chords subtending these.

Properties of chords, as measures of central and inscribed angles in circles, were familiar to the Greeks of Hippocrates' day, and it is likely that Eudoxus had used ratios and angle measures in determining the size of the earth and the relative distances of the sun and the moon.

In the works of Euclid there is no trigonometry in the strict sense of the word, but there are theorems equivalent to specific trigonometric laws or formulas. Propositions II. Theorems on the lengths of chords are essentially applications of the modern law of sines. We have seen that Archimedes' theorem on the broken chord can readily be translated into trigonometric language analogous to formulas for sines of sums and differences of angles.

In Book I of this treatise Menelaus establishes a basis for spherical triangles analogous to that of Euclid I for plane triangles. The second book of the Sphaerica describes the application of spherical geometry to astronomical phenomena and is of little mathematical interest. Book III, the last, contains the well known "theorem of Menelaus" as part of what is essentially spherical trigonometry in the typical Greek form — a geometry or trigonometry of chords in a circle.

In the circle in Fig. Menelaus and his Greek successors instead referred to AB simply as the chord corresponding to the arc AB. Instead we have an treatise, perhaps composed earlier ca. In this work Aristarchus made the observation that when the moon is just half-full, the angle between the lines of sight to the sun and the moon is less than a right angle by one thirtieth of a quadrant. In trigonometric language of today this would mean that the ratio of the distance of the moon to that of the sun the ration ME to SE in Fig.

For some two and a half centuries, from Hippocrates to Eratosthenes, Greek mathematicians had studied relationships between lines and circles and had applied these in a variety of astronomical problems, but no systematic trigonometry had resulted.

Then, presumably during the second half of the 2nd century BC, the first trigonometric table apparently was compiled by the astronomer Hipparchus of Nicaea ca. However, it appears that not until Hipparchus undertook the task had anyone tabulated corresponding values of arc and chord for a whole series of angles. It is possible that he took over from Hypsicles, who earlier had divided the day into parts, a subdivision that may have been suggested by Babylonian astronomy.

Ptolemy's Almagest. The theorem of Menelaus played a fundamental role in spherical trigonometry and astronomy, but by far the most influential and significant trigonometric work of all antiquity was composed by Ptolemy of Alexandria about half a century after Menelaus. We do not know when or where Euclid and Ptolemy were born.

We know that Ptolemy made observations at Alexandria from AD. Suidas, a writer who lived in the 10th century, reported that Ptolemy was alive under Marcus Aurelius emperor from AD to Ptolemy's Almagest is presumed to be heavily indebted for its methods to the Chords in a Circle of Hipparchus, but the extent of the indebtedness cannot be reliably assessed. It is clear that in astronomy Ptolemy made use of the catalog of star positions bequeathed by Hipparchus, but whether or not Ptolemy's trigonometric tables were derived in large part from his distinguished predecessor cannot be determined.

Similar reasoning leads to the formula [ It was the formula for sine of the difference — or, more accurately, chord of the difference — that Ptolemy found especially useful in building up his tables. Another formula that served him effectively was the equivalent of our half-angle formula.
