Extractions: Astronomy Brahmagupta Brahmagupta (c. 588 or c. 598 A.D. - c. 600 or 665 A.D.; India) Brahmagupta was a mathematician but he is also noted as being the last and most accomplished of all of the ancient Indian astronomers. In 628 A.D., Brahmagupta was the first person to use the mathematical concept of negative numbers to represent debts and positive numbers to represent assets as developed by the Hindus. It was Brahmagupta who developed the rules for the four operations ( addition, subtraction, multiplication and division) using negative numbers. Brahmagupta did not however present any definitions, axioms or theorems. Brahmagupta's two chief works were entitled, Khandakhadyaka and the Brahmasiddhanta. The Brahmasiddhanta, written in 628 A.D., opposed some of the Hindu findings on astronomy which had been established on a scientific basis in 476 A.D. It consisted of twenty-five chapters, twenty-three of which dealt with astronomy- most specifically lunar and solar eclipses, planetary conjunctions, lunar phases and the determination of the positions of the planet. The remaining two chapters dealt solely with mathematical concepts such as arithmetic progression, quadratic equations and the proving of geometrical theorems associated with surface and volume. In the Khandakhadyaka, Brahmagupta simply tried to simplify the already existing system. In the field of mathematics, Brahmagupta is most noted for his cyclic quadrilateral equation (Britannica, 2:461, 1994; Encyclopedia Americana, 4:410, 18:496, 24:614, 1991: and Barba, p. 64, 1995).

Extractions: multiply 26 5/6 by itself, the product is 720 1/36, so the difference in the square is 1/36. If we desire to make the difference smaller still than 1/36, we shall take 720 1/36 instead of 729 (or rather we should take 26 5/6 instead of 27), and by proceeding in the same way we shall find the resulting difference much less than 1/36.

It contains the first English translation (and the first translation into any western language) of any mathematical work of Brahmagupta, the greatest Indian mathematician of his period, as well as translations of the works on arithmetic and algebra by his successor Bhaskara II. Brahmagupta was born in 598 A.D. in northwestern India. His major work, the Brahmasphutasiddhanta (Correct Astronomical System of Brahma) was written when he was 30; the mathematical work translated here constitutes its 12th chapter. It treats the solution of linear and quadratic equations, and linear congruences, leading to the solution of the so-called Pell's equation ax2 + b = y2 (a and b being given integers and x and y integers to be found). This equation occurs for the first time in Brahmagupta's work, although it was misnamed by Euler after the 17th century English mathematician John Pell. Brahmagupta's work on Pell's equation was not really superseded until Fermat studied it a millennium later.

http://www.vidyapatha.com/scientists/brahmagupta.php

Extractions: The mathematician who first framed the rules of operation for zero was Brahmagupta. He was also to give a solution to indeterminate equations of the type ax2+1=y2 and the founder of a branch of higher mathematics called "Numerical analysis". No wonder Bhaskara, the great mathematician, conferred on him Ithe title of Ganakachakrachudamani, the gem of the circle of mathematicians. Brahmagupta was born at Bhillamala (Bhinmal), in Gujarat, in 598 A.D. He became court astronomer to I King Vyaghramukha of the Chapa dynasty. Of his two treatises, Brahmasphutasiddhanta and Karanakhandakhadyaka, the first is the more famous. It was a corrected version of the old astronomical text, Brahmasiddhanta. It was translated into Arabic, but erroneously titled Sind Hind. For several centuries the treatise remained a standard work of reference in India and the Arab countries. Brahmasphutasiddhanta also contains chapters on arithmetic and algebra. Brahmagupta's major contribution is the rules of operation for zero. He declared that addition or subtraction of zero to or from any quantity,negative or positive, does not affect it. He also added that the product of any quantity with zero is zero and division of any quantity by zero is infinity. He,however, wrongly claimed that division of zero by zero was zero.

Extractions: He was head of the astronomical observatory at Ujjain which was the foremost mathematical centre of ancient India. He wrote important works on mathematics and astronomy. Brahmagupta's understanding of the number system was far beyond other mathematicians of that period. Brahmagupta was born at Bhillamala (Bhinmal), in Gujarat, in 598 AD. He became court astronomer to King Vyaghramukha of the Chapa dynasty. His major contribution is the rules of operation of zero. He declared that addition or subtraction of zero to or from any quantity, negative or positive, does not affect it. He also found out that the product of any quantity with zero is zero and division of any quantity by zero is infinity. He, however, wrongly claimed that division of zero by zero was zero (actually this division is not defined). He also framed rules to solve a simple execution of the type ax+b = , as well as methods to sum up geometric series. Besides, he noted the difference between algebra and arithmetic and so was the first mathematician to treat them as two separate branches of mathematics. He was also the first astronomer to use algebra in calculations.

En algèbre notamment Brahmagupta établit une méthode générale pour trouver les solutions entières d'une équation du second degré. Il emploie, pour désigner l'inconnue le mot varõa qui veut dire ordinairement ``couleur'' mais aussi ``lettre'', sans doute parce que dans le calcul même les inconnues étaient représentées par des lettres. Mais, plus tard, les textes algébriques ont utilisé les noms des couleurs ou leurs lettres initiales pour distinguer les inconnues. L'Inde classique de Jean Filliozat et Louis Renou. Retour

Extractions: Rare Book Room Exhibit BRAHMAGUPTA (598 - ). Algebra, with Arithmetic and Mensuration . London: 1817. Brahmagupta (b. 598) was one of the great mathematicians of the "high period" of Hindu mathematics (200-1200). Most of their work was motivated by astronomy and astrology. More than thirteen centuries ago, Brahmagupta wrote: "As the sun eclipses the stars by its brilliancy, so the man of knowledge will eclipse the fame of others in assemblies of people if he proposes algebraic problems, and still more if he solves them." This point of view is still held by many mathematicians even today.

Extractions: David D. Bleecker and Lawrence J. Wallen A taco is the solid formed by bending a circular tortilla around a cylinder and filling it to the border. A natural problem is to find the cylinder that yields the taco of largest volume for a tortilla of a unit radius. For circular cylinders the volume of the taco is a Bessel function of the cylinder's radius, and for cylinders with other familiar cross-sections the volume of the corresponding taco also involves special functions. But in each case, with the aid of a computer algebra system the methods of calculus can be applied to find the taco of maximal volume. However, the general case is a nontrivial problem in the calculus of variations. The existence of a taco of maximal volume for a suitably general class of cylinders can be proved, and numerical experiments are given to show how the shape and volume of this "world's largest taco" can be approximated.
