He stressed the importance of these topics as a qualification for a mathematician, or calculator ganaka. He studied the five traditional siddhanthas on Indian astronomy as well as the work of other astronomers including Aryabhata ILatadeva, Pradyumna, VarahamihiraSimha, Srisena, Vijayanandin and Vishnuchandra.

The court of Caliph Al-Mansur — received an embassy from Sindh, including an astrologer called Kanaka, who brought possibly memorised astronomical texts, including those of Brahmagupta. Scholars state that he incorporated a great deal of originality to his revision, adding a considerable amount of new material. He further gave rules of using zero with negative and positive numbers.

Also, if m and x are rational, so are dab and c. At the bottom of the article, feel free to list any sources that support your changes, so that we can fully understand their context.

Here Brahmagupta uses names of objects to represent the digits of place-value numerals, as was common with numerical data in Sanskrit treatises. One theorem gives the lengths of the two segments a triangle’s base is divided into by its altitude:.


Each yuga is progressively shorter than the preceding one, corresponding to a decline in the moral and physical state of humanity. Brahmagupta wrote two main texts, both of which deal with arithmetic and astronomy.

Progenitors represents the 14 Progenitors “Manu” in Indian cosmology or 14, “twins” means 2, “Ursa Major” represents the seven stars of Ursa Major or 7, “Vedas” refers to the 4 Vedas or 4, dice represents the number of sides of the tradition die or 6, and so on. In mathematics, biogaphy contribution to geometry was especially significant. It was translated into Arabic in Baghdad about and had a major impact on Islamic mathematics and astronomy.

In addition to expounding on traditional Indian astronomy in his books, Brahmagupta devoted several chapters of Brahma-sphuta-siddhanta to mathematics. He was well-read in the five traditional siddhanthas on Indian astronomy, and also studied the work of other ancient astronomers such as Aryabhata I, Latadeva, Pradyumna, Varahamihira, Simha, Srisena, Vijayanandin and Vishnuchandra. The product of the first [pair], multiplied by the multiplier, with the product of the last [pair], is the last computed.

He was among the few thinkers of his era who had realized that the earth was not flat as many believed, brahmagupt a sphere.

For the volume of a frustum of a pyramid, he gives the “pragmatic” value as the depth times the square of the mean of the edges of the top and bottom faces, and he gives the “superficial” volume as the depth times their mean area.

Brahmagupta Biography

Brahmagupta dedicated a brahmwgupta portion of his work to geometry. He established a formula for the biographhy of cyclic quadrilaterals derived from Heron’s formulaand continued Diophantus’ work by characterizing all the solutions of linear congruences, and by proposing the quadratic Diophantine equation which nowadays is known as Pell equation. Sometime in the eighth century the work of Brahmagupta was brahmagupts to Baghdad where it was translated into Arabic and then subsequently it was translated into Latin, at which point it spread throughout the western world.


His main, but not sole, achievements in the field of mathematics were the introduction of zero and negative numbers. The work is thought to be a revised version of the received siddhanta of the Brahmapaksha school, incorporated with some of his own new material.


Imaging two triangles within [a cyclic quadrilateral] with unequal sides, the two diagonals are the two bases. By using this site, you agree boography the Terms of Use and Privacy Policy.

This entry contributed by Margherita Barile Hindu astronomer and mathematician who applied algebraic methods to astronomical problems. The key to his solution was the identity, [24]. When a positive is to be subtracted from a negative or a negative from a positive, then it is to be added.

The procedures for finding the cube and cube-root of an integer, however, are described compared the latter to Aryabhata’s very similar formulation. Articles bigoraphy Britannica Encyclopedias for elementary and high school students. Like many Indian mathematicians of this and later periods, Brahmagupta was producing work that was many centuries ahead of the equivalent work being carried out in the western world. Brahmagupta distinguished twenty arithmetical operations logisticsincluding the extraction of roots and the solution of proportions, and eight measurements determinations.

The brightness is increased in the direction of the sun. The two [lower segments] of the two diagonals are two brahmagypta in a triangle; the brwhmagupta [of the quadrilateral is the base of the triangle].

Diminish by the middle [number] the square-root of the rupas multiplied by four times the square and increased by the square of the middle [number]; divide the remainder by twice the square. Identify Actors By Eyes.

He is also known as Aryabhata I or Aryabhata the Elder to distinguish him from a 10th-century Indian mathematician…. He also had a profound and direct influence on Islamic and Byzantine astronomy. Primarily a book of astronomy, it also contains several chapters on mathematics.
