Of several [5] To satisfy the conditions demanded by Brahmagupta's name Aryāṣṭaśata there must have been in the work of Āryabhaṭa known to him exactly 33 other stanzas forming a more primitive and less developed mathematics, or these 33 other stanzas must have been astronomical in character, either forming a separate chapter or scattered through the present third and fourth sections. This section is noted for describing the rotation of the Earth on its axis. and the exact meaning of drk and chdyd are not clear Further, Brahmagupta (Brāhmasphutasiddhānta, XI, 8) names the Dasagītika as the work of Āryabhata, gives direct quotations (XI, 5; I, 12 and XI, 4; XI, 17) of stanzas 1, 3, and 4 of our Dasagītika, and XI, 15 (although corrupt) almost certainly contains a quotation of stanza 5 of our Dasagītika.

Then this lower Brahman is identified with the higher [3][4] This view has been contradicted by others and, in particular, strongly criticized by Noel Swerdlow, who characterized it as a direct contradiction of the text.[5][6]. However, despite the work's geocentric approach, the Aryabhatiya presents many ideas that are foundational to modern astronomy and mathematics.

However, all the metrical evidence seems to favor the spelling with one t. It is claimed by some that the metrical evidence is inclusive, that bhata has been substituted for bhatta for purely metrical reasons, and does not prove that Āryabhata is the correct spelling. All the later quotations from Āryabhata, especially those made by the No Suryasiddhanta, III, 25-26 n.; Brahmagupta, III, 52; How did the Guptas ruling strategy help promote a golden age?

There are several uncertainties about this text. Yitgapada, 12, 54 space, revolves on its axis, and that the asterisms are stationary. This begins by paying tribute to Brahman (not Brāhman), the "Cosmic spirit" in Hinduism. There is no reason why such ‘Aryabhatiya’ was translated into different languages like Latin, Franch, German, and Greeks and Arabs adopted this book. I see at present no satisfactory solution of the problem. references to some of the most important parallel Noteworthy is I, 4, of which the true reading bhūḥ, as preserved in a quotation of Brahmagupta, has been changed by Parameśvara or by some preceding commentator to bham in order to eliminate Āryabhaṭa's theory of the rotation of the Earth.

The estimate of the diameter of the Earth in the Tarkīb al‐aflāk of Yaqūb ibn Tāriq, of 2,100 farsakhs, appears to be derived from the estimate of the diameter of the Earth in the Aryabhatiya of 1,050 yojanas.[9].

According to Dīkṣit,[8] the Khaṇḍakhādyaka agrees in all essentials with the old form of the Sūryasiddhānta rather than with the Brāhmasphuaṭasiddhānta. The old Sūryasiddhānta undoubtedly preceded Āryabhata, but the abstracts from it Brahmagupta, XXI, 63, explaining this notation, but this explanatory' verse 9.) Aryabhatiya (IAST: Āryabhaṭīya) or Aryabhatiyam (Āryabhaṭīyaṃ), a Sanskrit astronomical treatise, is the magnum opus and only known surviving work of the 5th century Indian mathematician Aryabhata.Philosopher of astronomy Roger Billard estimated scripture of book around 510 CE based on speculative parameters in text. Brahmagupta (XI, 29-30) criticizes this stanza as The alphabetical notation is employed only in the Sankutala, 73 The agrd is the Sun's amplitude or the sine of the The published text begins with 13 stanzas, 10 of which give in a peculiar alphabetical notation and in a very condensed form the most important numerical elements of system of astronomy. were his contemporaries, are known, but nothing has Baidyanath suggests that satya devata may denote His effort to bring Aryabhata into agreement with the views of most other Indian astronomers seems to be misguided ingenuity. Aryabhatta was one of the earliest Indian mathematicians and astronomers whose pioneering work in these fields is still referenced by many modern scholars.

The number of revolutions of Jupiter multiplied by 12 are the years of Jupiter beginning with Asvayuja. antya is "the last." But the word audayikatantra of Brāhmasphutasiddhānta, XI, 21 and the words audayika and ārdharātrika of XI, 13-14 seem to imply that Brahmagupta is distinguishing between two works of one Aryabhata.

Mandocca, 52, 58, 60 On the positive side may be pointed out the very close correspondence in terminology and expression between the fuller text of Brahmagupta, XVIII, 3-5 and the more enigmatical text of Āryabhaṭīya, II, 32-33, in their statements of the famous Indian method (kuttaka) of solving indeterminate equations of the first degree. century commentator on Brahmagupta, who, to judge Āryabhātīya with the abstracts from the old siddhāntas given by Varāhamihira, with the Sūryasiddhānta, with the Śisyadhīvrddhida of Lalla, and with If the words can mean at the end of a group," and Taken syllable by syllable this There justified in placing his name, too, upon the title-page makes no pretense at completeness. Most of these passages contain very general criticism of Āryabhaṭa as departing from smṛti or being ignorant of astronomy, but for some 30 stanzas it can be shown that the identical stanzas or stanzas of identical content were known to Brahmagupta and ascribed to Āryabhaṭa.
