Brahmagupta was an Ancient Indian astronomer and mathematician who lived from AD to AD. He was born in the city of Bhinmal in Northwest India. Brahmagupta, whose father was Jisnugupta, wrote important works on mathematics and astronomy. In particular he wrote Brahmasphutasiddhanta Ⓣ, in The field of mathematics is incomplete without the generous contribution of an Indian mathematician named, Brahmagupta. Besides being a great.

His remaining eighteen sines are,,,, The square of a negative or of a positive is positive; [the square] of zero is zero. Carl Gustav Jacob Jacobi German. He was among the few thinkers of his era who had realized that the earth was not flat as many believed, but a sphere. The key to his solution was the identity, [24].

The additive is equal to the product of the additives.

When it is divided by the multiplier increased by two it is the leap of one of the two who make the same journey. He also introduced new methods for solving quadratic equations and gave equations to solve systems of simultaneous indeterminate equations, in addition to providing two equivalent solutions brahmavupta the general quadratic equation.

If the moon were above the sun, how would the power of waxing and waning, etc. The accurate [values] are the square-roots from the squares of those two multiplied by ten. Brahmagupta was an orthodox Hindu, and his religious views, particularly the Hindu yuga system of measuring the ages of mankind, influenced his work. Help us improve this article!

The diameter and the square of the radius [each] multiplied by 3 are [respectively] the practical circumference and the area [of a circle]. In addition to expounding on traditional Indian astronomy in his books, Brahmagupta devoted several chapters of Brahma-sphuta-siddhanta to mathematics. The book is written in arya-meter comprising verses and 24 chapters.


Lalla and Bhattotpala in the 8th and 9th centuries wrote commentaries on the Khanda-khadyaka.

The square-root of the sum of the two products of brahmatupta sides and opposite sides of a non-unequal quadrilateral is the diagonal. Aryabhataastronomer and the earliest Indian mathematician whose work and history are available to modern scholars.

He also gave rules for dealing with five types of combinations of fractions. The next formula apparently deals with the volume of a frustum of a square pyramid, where the “pragmatic” volume is the depth times the square of the mean of the edges of the top and bottom faces, while the “superficial” volume is the depth times their mean area. Addition was indicated by juxtaposition, subtraction by placing a dot over the subtrahend, and division by brahmagupa the divisor below the dividend, as in our fractional notation but without the bar.

Scholars state that he incorporated a great deal of originality to his revision, adding a considerable amount of new material. He went on to solve systems of simultaneous indeterminate equations stating that the desired variable must first be isolated, and then the equation must be divided by the desired variable’s coefficient.

The city was a center of learning for mathematics and astronomy, and he flourished as an astronomer in the intellectual atmosphere of the city. brahmagkpta

As a young man he studied astronomy extensively. Almost years later, in the 12th Century, another Indian mathematician, Bhaskara II, showed that the answer should be infinity, not zero on the grounds that 1 can be divided mathematucian an infinite number of pieces of size zeroan answer that was considered correct for centuries.

In addition to his work on solutions to general linear equations and quadratic equations, Brahmagupta went yet further by considering systems of simultaneous equations set of equations containing multiple variablesand solving quadratic equations with two unknowns, something which was not even considered in the West until a thousand years later, when Fermat was considering similar problems in 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.


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. Prithudaka Svamina later commentator, called him Bhillamalacharyathe teacher from Bhillamala.

Brahmagupta dedicated a substantial portion of his work to geometry and trigonometry. He further gives a theorem on rational triangles.

He also gave a valuable interpolation formula for computing sines. In his work on arithmetic, Brahmagupta explained how to find the cube and cube-root of an integer and gave rules facilitating the computation of squares and square roots. 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. It was translated into Arabic in Baghdad about and had a major impact on Islamic mathematics and astronomy.

Your contribution may be further edited by our staff, and its publication is subject to our final approval. He is believed to have lived and worked in Bhinmal in present day Rajasthan, India, for a few years. Its perpendicular is the lower portion of the [central] perpendicular; brahmagupha upper portion of the [central] perpendicular is half of the sum of the [sides] perpendiculars diminished by the lower [portion of barhmagupta central perpendicular].
