At the end of a bright [i.e. [...][32], 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.[31]. As a result, Brahmagupta is often referred to as Bhillamalacarya, that is, the teacher from Bhillamala Bhinmal. Mathematics is the study of topics such as quantity (numbers), structure, space and change. Further work exploring the longitudes of the planets, diurnal rotation, lunar and solar eclipses, risings and settings, the moon's crescent and conjunctions of the planets, are discussed in his treatise Khandakhadyaka.

In chapters 12 and 18 in particular, he laid the foundations of the two major fields of Indian mathematics, pati-ganita (“mathematics of procedures,” or algorithms) and bija-ganita (“mathematics of seeds,” or equations), which roughly correspond to arithmetic (including mensuration) and algebra, respectively. When was brahmagupta born? He severely criticized Jain cosmological views and other heterodox ideas, such as the view of Aryabhata (born 476) that the Earth is a spinning sphere, a view that was widely disseminated by Brahmagupta’s contemporary and rival Bhaskara I. Brahmagupta’s fame rests mostly on his Brahma-sphuta-siddhanta (628; “Correctly Established Doctrine of Brahma”), an astronomical work that he probably wrote while living in Bhillamala, then the capital of the Gurjara-Pratihara dynasty.

Brahmagupta saw himself as an astronomer who did mathematics, nut he is mostly remembers to the contributions he made to mathematics. Brahmagupta was born and grew up in western India. Brahmagupta, (born 598—died c. 665, possibly Bhillamala [modern Bhinmal], Rajasthan, India), one of the most accomplished of the ancient Indian astronomers. Brahmagupta was an Indian mathematician, born in AD in Bhinmal, a state of Rajhastan, India. Although Brahmagupta does not explicitly state that these quadrilaterals are cyclic, it is apparent from his rules that this is the case. Even though most scholars assume that Brahmagupta was born in Bhillamala, there is no conclusive evidence for it. One of his quotes accurately portrays who he was. He further gives a theorem on rational triangles. Even though most scholars assume that Brahmagupta was born in Bhillamala, there is no conclusive evidence for it. This leads up to Brahmagupta's famous theorem, 12.30–31. q + s/2 while, letting t = p + q + r + s/2, the exact area is. Quick Info Born 598 (possibly) Ujjain, India Died 670 India Summary Brahmagupta was the foremost Indian mathematician of his time. Born in Northwest India, Brahmagupta was a son of an astrologer. In addition to expounding on traditional Indian astronomy in his books, Brahmagupta devoted several chapters of Brahma-sphuta-siddhanta to mathematics. Brahmagupta was born in c. 598, perhaps in the astronomically significant ancient Indian city of Ujjain—a place near the tropic of cancer that occupies a place in Indian history somewhat comparable to that of Greenwich in England. The square-root of the sum of the two products of the sides and opposite sides of a non-unequal quadrilateral is the diagonal. So, in a "non-unequal" cyclic quadrilateral (that is, an isosceles trapezoid), the length of each diagonal is √pr + qs. He was the head of the astronomical observatory at Ujjain which was the center of mathematics in India witnessing the work of many extraordinary mathematicians. He spent most of his life in Bhinmal which was under the rule of King Vyaghramukha. Such a great Mathematician was born in 598 CE in Bhinmal, the Indian state of Rajasthan at present. [17], 12.40.
