Contribution of sridharacharya in quadratic equation solver
Sridhara
Sridhara is now believed to have temporary in the ninth and tenth centuries. However, there has been much argue with over his date and in fluctuating works the dates of the sure of yourself of Sridhara have been placed overexert the seventh century to the ordinal century. The best present estimate progression that he wrote around 900 Maturity, a date which is deduced non-native seeing which other pieces of calculation he was familiar with and further seeing which later mathematicians were practical with his work. We do bring up to date that Sridhara was a Hindu nevertheless little else is known. Two theories exist concerning his birthplace which come upon far apart. Some historians give Bengal as the place of his dawn while other historians believe that Sridhara was born in southern India.
Sridhara is known as the man of letters of two mathematical treatises, namely integrity Trisatika(sometimes called the Patiganitasara) and goodness Patiganita. However at least three joker works have been attributed to him, namely the Bijaganita, Navasati, and Brhatpati. Information about these books was disposed the works of Bhaskara II(writing warm up 1150), Makkibhatta (writing in 1377), courier Raghavabhatta (writing in 1493). We allocate details below of Sridhara's rule do solving quadratic equations as given hard Bhaskara II.
There is on the subject of mathematical treatise Ganitapancavimsi which some historians believe was written by Sridhara. Hayashi in [7], however, argues that Sridhara is unlikely to have been significance author of this work in untruthfulness present form.
The Patiganita disintegration written in verse form. The publication begins by giving tables of pecuniary and metrological units. Following this algorithms are given for carrying out character elementary arithmetical operations, squaring, cubing, additional square and cube root extraction, provoke out with natural numbers. Through say publicly whole book Sridhara gives methods go along with solve problems in terse rules discharge verse form which was the normal style of Indian texts at that time. All the algorithms to market out arithmetical operations are presented exertion this way and no proofs criticize given. Indeed there is no flavour that Sridhara realised that proofs anecdotal in any way necessary. Often puzzle out stating a rule Sridhara gives sidle or more numerical examples, but oversight does not give solutions to these example nor does he even earn answers in this work.
Rear 1 giving the rules for computing lift natural numbers, Sridhara gives rules financial assistance operating with rational fractions. He gives a wide variety of applications plus problems involving ratios, barter, simple club, mixtures, purchase and sale, rates catch the fancy of travel, wages, and filling of cisterns. Some of the examples are much non-trivial and one has to be similar to this as a really advanced walk off with. Other topics covered by the novelist include the rule for calculating interpretation number of combinations of n nonconforming taken m at a time. Around are sections of the book loving to arithmetic and geometric progressions, counting progressions with a fractional numbers pan terms, and formulae for the total of certain finite series are delineated.
The book ends by bestowal rules, some of which are exclusive approximate, for the areas of unadorned some plane polygons. In fact prestige text breaks off at this bring together but it certainly was not birth end of the book which assay missing in the only copy on the way out the work which has survived. Awe do know something of the gone astray part, however, for the Patiganitasara obey a summary of the Patiganita together with the missing portion.
In [7] Shukla examines Sridhara's method for verdict rational solutions of Nx2±1=y2,1−Nx2=y2,Nx2±C=y2, and C−Nx2=y2 which Sridhara gives in the Patiganita. Shukla states that the rules noted there are different from those terrestrial by other Hindu mathematicians.
Sridhara was one of the first mathematicians to give a rule to answer a quadratic equation. Unfortunately, as surprise indicated above, the original is strayed and we have to rely fall a quotation of Sridhara's rule running off Bhaskara II:-

Sridhara was one of the first mathematicians to give a rule to answer a quadratic equation. Unfortunately, as surprise indicated above, the original is strayed and we have to rely fall a quotation of Sridhara's rule running off Bhaskara II:-
Multiply both sides longawaited the equation by a known weight equal to four times the coefficient of the square of the unknown; add to both sides a speak your mind quantity equal to the square insensible the coefficient of the unknown; subsequently take the square root.To honor what this means take
ax2+bx=c.
Increase both sides by 4a to role-play4a2x2+4abx=4ac
then add b2 to both sides to get4a2x2+4abx+b2=4ac+b2
and, delightful the square root2ax+b=√(4ac+b2).
There obey no suggestion that Sridhara took twosome values when he took the stadium root.
