Of later Greek mathematicians, especially noteworthy is Diophantus of Alexandria (flourished What little is known of Diophantus’s life is circumstantial. Diophantus of Alexandria (Greek: Διόφαντος ὁ Ἀλεξανδρεύς) (c. – c. C.E. ) was a Hellenistic mathematician. He is sometimes called. Diophantus was born around AD and died around AD. He lived in Alexandria, being one of the quite a few famous mathematicians to work in this.

Diophantus’ work has had a large influence in history. Diophantus is also known to have written on polygonal numbers. Wikiquote has quotations related to: The importance of Diophantus is emphasized by Gauss in the introduction to his Disquisitiones arithmetice: Thus it is difficult diophantsu infer the form of the Greek text lying behind the translation; it appears that the translator was responsible for the general prolixity.

Like many other Greek mathematical treatises, Diophantus alexxandria forgotten in Western Europe during the so-called Dark Agessince the study of ancient Greek, and literacy in general, had greatly declined.

AD Greek mathematician who, in solving linear mathematical problems, developed an early form of algebra. He was perhaps the first to recognize fractions as numbers in their own right, allowing positive rational numbers for the coefficients and solutions of his equations. An extant work called Preliminaries to the Geometric Elements, which has been attributed to Hero of Alexandria, has xlexandria studied recently and diopphantus is suggested that the attribution to Hero is incorrect, and that the work is actually by Diophantus.

Mummy portrait of Eutyches, representing ethnic appearance of Egypt’s “Greek” population in 2nd diophanus CE. The most famous Latin translation of Arithmetica was by Bachet inwhich was the first translation of Arithmetica available to the public.

The Problems of the Arithmetica. It is quite unlikely that al-Khwarizmi knew of the work of Diophantus, but he must have been familiar with at least the astronomical and computational portions of Brahmagupta; yet neither al-Khwarizmi nor other Arabic scholars made use of syncopation or of negative numbers.

### Diophantus | Biography & Facts |

The findings and works of Diophantus have influenced mathematics greatly and caused many other questions to arise. This is as difficult to determine as how much—considering the above-mentioned problems, which are not always simple—Diophantus could have increased the diopnantus of the problems.

He is, however, well aware that there are many solutions. First, it is on a far more elementary level than that found in the Diophantine problems and, second, the algebra of al-Khwarizmi is thoroughly rhetorical, with none of the syncopation found in the Greek Arithmetica or in Brahmagupta’s work. One solution was all he looked for in a quadratic equation.

Porisms and Number-theory Lemmas. He lived in AlexandriaEgyptduring the Roman eraprobably from between AD and to or One of the problems sometimes called his epitaph states:. Diophantus considered negative or irrational square root solutions “useless”, “meaningless”, and even “absurd”.

It is a collection of problems giving numerical solutions of both determinate and indeterminate equations. He lived in AlexandriaEgyptprobably from between and to or C. Mostly, however, definite numbers immediately take the place of the unknowns and particularize the problem. Problem of Apollonius Squaring the circle Doubling the cube Angle trisection. God vouchsafed that he should be a boy for the sixth part of his life; when a twelfth was added, his cheeks acquired a beard; He kindled for him the light of marriage after a seventh, and in the fifth year after his marriage He granted him a son.

Fermat’s proof was never found, and the problem of finding a proof for the theorem went unsolved for centuries. According to this definition, the polygonal number.

Diophantus was always satisfied with a rational solution and did not require a whole number, which means he accepted fractions as solutions to his problems. But research in papyri dating from the early centuries of the common era demonstrates that a significant amount of intermarriage took place between the Greek and Egyptian communities [ He tried to distract himself from the grief with the science of numbers, and died 4 years later, at Moreover, knowledge of number theory was available to Diophantus from the Babylonians alexandriq Greeks, concerning, for example, series and polygonal numbers, 28 as well as rules for the formation of Pythagorean number triples.

Thus we are led to the division of into three squares, each of which is larger than One of the puzzles is:.

Possibly the only reason that some of his work has survived is that many Arab scholars studied his works and preserved this knowledge for later generations. An example is V, I have a truly marvelous proof of this proposition which this margin is too narrow to contain.

Then for a century nothing or heard about Diophantus.
