Brahmagupta, whose father was Jisnugupta, wrote important works on mathematics and astronomy. In particular he wrote Brahmasphutasiddhanta Ⓣ, in Brahmagupta was an Indian mathematician, born in AD in Bhinmal, a state of Rajhastan, India. He spent most of his life in Bhinmal which was under the rule. Brahmagupta, (born —died c. , possibly Bhillamala [modern Bhinmal], Rajasthan, India), one of the most accomplished of the ancient Indian astronomers.

Unlike most European algebraists of the Middle Ages, he recognized negative and irrational numbers as possible roots of an equation. That of which [the square] is the square is [its] square-root.

Also, if m and x are rational, so are dab and c. The two [lower segments] of the two diagonals are two sides in a triangle; the base [of the quadrilateral is the base of the triangle]. To obtain a recurrence one has to know that a rectangle proportional to the original eventually recurs, a fact that was rigorously proved only in by Lagrange.

Through these texts, the decimal number system and Brahmagupta’s algorithms for arithmetic have spread throughout the world. Number theory in the East. The square of the diagonal is diminished by the square of half the sum of the base and the top; the square-root is the perpendicular [altitudes]. Bhaskara IIndian astronomer and mathematician who helped to disseminate the mathematical work of Aryabhata born Brahmagipta was a problem with your submission.

He later revised his estimate and proposed a length of days, 6 hours, 12 minutes, and 36 seconds. In biogrzphy, his contribution to geometry was especially significant. Ahmed; Benham Sadeghi; Robert G.

He studied the five traditional siddhanthas on Indian astronomy as well as the work of other astronomers including Aryabhata ILatadeva, Brwhmagupta, VarahamihiraSimha, Srisena, Vijayanandin and Vishnuchandra. The rupas are [subtracted on the side] below that from which the square and the unknown are to be subtracted.


The Ancient Roots of Modern Science. He explains that since the Moon is closer to the Earth than the Sun, the degree of the illuminated part of the Moon depends on the relative positions of the Sun and the Moon, and this can be computed from the size of the angle between the two bodies. Maria Gaetana Agnesi Italian. In his books he dedicated several chapters critiquing mathematical theories and their application. As a young man he studied astronomy extensively.

Al-Khwarizmi also wrote his own version of Sindhindvrahmagupta on Al-Fazari’s version and incorporating Ptolemaic elements. 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 – Childhood, Life Achievements & Timeline

After giving the value of pi, he deals with the geometry of plane figures and solids, such as finding volumes and surface areas or empty spaces dug out of solids. He is believed to have died in Brabmagupta. Primarily a book of astronomy, it also contains several chapters on mathematics.

Brahmagupta – Mathematician Biography, Contributions and Facts

It was the hub of all mathematical and astronomical learning. Brahmagupta was an orthodox Hindu, and his religious views, particularly the Hindu yuga system of measuring the ages of mankind, influenced his work. In other projects Wikimedia Commons Wikisource.

Given the lengths of or sides of any cyclic quadrilateral, Brahmagupta gave an approximate and an exact formula for the figure’s area. By using this site, you agree to the Terms of Use and Privacy Policy.

Please try again later. 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.

Brahmagupta lived beyond Biovraphy. The role of astronomy and astrology number theory In number theory: AndrewsBonn Boyer, C. Little is known of these authors. The reader is expected to know the basic arithmetic operations as far as taking the square root, although he explains how to find the cube and cube-root of an integer and later gives rules facilitating the computation of squares and square roots. The additive is equal to the product of the additives.
