The commentators include Bhaskara and Brahmagupta among other notables.

He mentions proportions of triangles with respect to shadows. This is a yoga of the Sun and Moon when they are in different ayanas aryanhatiya, have the same declination, and the sum of their longitudes is degrees.

Aryabhata’s formulas for finding these presuppose knowledge of the quadratic equation. Next, Aryabhata lays out the numeration system used in the work. It engpish probable to me that Brahmagupta had before him these two stanzas in their present form.

The quadrilateral is made by constructing two triangles, one on each side of the diagonal. In Aryabhata’s time the prevailing view of the cosmos was that the Earth was stationary and the sun, moon, other planets, and everything else in the sky rotated around it. By this rule the relation of the circumference to diameter is given. The sine of the distance between the Sun and the zenith at midday of the egnlish day is the equinoctial sine. It is written in the Sanskrit language, the language of the Aryans – the people from Europe who migrated to India around B.

As regards length, without commentary the Aryabhatiya would barely constitute a pamphlet. I have thought it better to publish the material as it is rather than to postpone publication for an indefinite period.

Contrary to a later popular Western belief that the moon is made of cheese, Aryabhata believed that: University of Chicago Press: At present the evidence is too scanty to allow us to aryabatiya the sources from which Aryabhata drew.

In fact, some later commentaries on the Aryabhatiya by notable mathematicians attempted to reconcile Aryabhata’s findings with their belief in a stationary Earth.

In stanza 1 the syllable su in the phrase which gives the revolutions of the Earth is a misprint for bu as given correctly in the commentary. The Moon consists of water, the Sun of fire, the Earth of earth, and the Earth’s shadow of darkness. As Fleet remarks, [15] Aryabhata here claims specifically as his work only three chapters. After giving this value without derivation or explanationAryabhata briefly describes the method by which he derived his sine table shown above.

At any rate, the context shows that the rule deals with the actual construction of plane figures. A Concise History of India. Aryabhatiiya is not a complete and detailed working manual of mathematics and astronomy.

However, I know no other passage which, would warrant such a translation of antyavarge.

There is no good reason for refusing to take them in the same sense here. Compare II, 2, where in giving the names of classes of numbers he uses the expression sthanat sthanam dasagunam syat”from place to place each is ten times the preceding. Ya is equal to the sum of na and ma. This innovation allows for advanced arithmetical computations which would have been considerably more difficult without it.

The words varga and avarga seem to refer to the Indian method of extracting the square root, which is described in detail by Rodet [26] and by Avadhesh Narayan Singh. Jain mathematicians also excelled at mathematics prior to Aryabahtiya.

### Aryabhatiya – Wikipedia

Aryabhata numerationthe Sanskrit numerals. Needless to say, the explanation is quite cryptic. Ganguly finds justification for this interpretation p. It is a preliminary study based on inadequate material. Is it intended merely as a statement of the popular view? The text is written in Sanskrit and divided into four sections, covering a total of verses that describe different results using a mnemonic style typical for such works in India.

That is, he used letters of the alphabet to form words with consonants giving digits and vowels denoting place value. Madhyajya, 74 Madhyahnat krama, 80 Mando, 60, 61 Mandakarzia, 61 Mandagati, 59 Mandaphala, Mandocca, 52, 58, 60 Mithydjnana, 9, 14, 65, 67 Mma, 63 Mesa, 9, 11, 16, 60, 63, Then this lower Brahman is identified with the higher Brahman as being only an individuafized manifestation of the latter.

## The Aryabhatiya of Aryabhata

There is no good reason why the thirteen stanzas should not have been named Dasagitika as they are named by Aryabhata himself in stanza C from the ten central stanzas in Giti meter which give the astronomical elements of the system. Therefore the vowel a used in varga and avarga places with varga and avarga letters refers the varga letters k to m to the first varga place, the unit place, multiplies them by 1.

Whatever the meaning may be, the passage is of no consequence for aryabhhatiya numbers actually dealt with by Aryabhata in this treatise.

Moon, and planets m, 9 years of, equal revolutions of Sun, 15 Yitgapada, 12, 54 Yoga, of Sun and Earth, 52, 81 Yojana, measure of increase and. Perhaps this is from whence Aryabhata estimated the circumference of the Earth. The varga or “square” places are the first, third, fifth, etc. Next, Aryabhata says that the product of two equal quantities, the area of a square, and a square are equivalent and likewise, the product of three quantities and a solid with 12 edges are equivalent.

Only nine symbols may have been in use and a blank column may have served to represent zero. Bibhutibhusan Datta, [37] in criticism of the number of revolutions of the planets reported by Alberuni II,remarks that the numbers given for the revolutions of Venus and Aryxbhatiya really refer to the revolutions of their apsides.

It would be more accurate to say “conjunctions. The discrepancy offers no firm support to the contention of Kaye that this stanza is a later addition. Foundations of Indian Mathematics William J.

The Aryabhatiya is written in poetic verse – typical of Sanskrit works – and seems to be more like a collection of enhlish and mnemonic devices to aid in teaching mathematical and astronomical ideas than a traditional text. He then gives an overview of his astronomical findings.
