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.

Ah, what a marvel! Furthermore, every number is the sum of two V, 9three V, 11or four IV, 29, and 30; V, 14 square numbers.

Diophantus of Alexandria – Wikisource, the free online library

A Greek text of Diophantus was available only in Byzantium, where Michael Psellus saw what was perhaps the only copy still in existence. Many scholars and researchers believe that The Porisms may have actually been a section included inside Arithmetica or indeed may have been the rest of Arithmetica. A Dipphantus of Mathematics: He lived in AlexandriaEgyptduring the Roman eraprobably from between AD and to or In this case one cannot say whether the proposition was proved. The most famous Latin translation of Arithmetica was qlexandria Bachet in which was the first translation of Arithmetica available to the public.

Some of the limitations of Diophantus’ notation are that he only had notation for one unknown and, when problems involved more than a single unknown, Diophantus was reduced to expressing “first unknown,” “second unknown,” etc. Archimedes Dicaearchus Zeno of Elea. Algebra still had a long way to go before very general problems could be written down and solved succinctly.


Diophantus of Alexandria Ancient Greek: The History of Mathematics: Learn More in these related Britannica articles: Most scholars consider Diophantus to have been a Greek, [1] though it has been suggested that he may have been a Hellenized Babylonian. AD Greek mathematician who, in solving linear mathematical problems, developed an early form of algebra. He also considered simultaneous quadratic equations.

How to find two square numbers having a given difference has been shown in He lived in AlexandriaEgyptprobably from between and to or C.

Diophantus of Alexandria

Arithmetica On Sizes and Distances Hipparchus. Further renumbering is unlikely; it is fairly certain that the Byzantines only knew the six books they transmitted and the Arabs no more than Books I to VII in the commented version.

This gives a hypotenuse of xsince 3 x: Diophantus’ work created a foundation for work on algebra and, in fact, much of advanced mathematics is based on algebra. This problem has already been solved in IV.

Nesselmann, Die Algebra der Griechen Berlin,pp. Again using the result of Such examples motivated the rebirth of number theory. Further examples of solution by approximation are:. It is impossible, as Hankel has remarked, even after studying the hundredth solution, to predict the form of the hundred-and-first.

Before him everyone wrote out equations completely. Historia Matematica, New York,Vol. This tomb holds Diophantus.

In Books IV to VII Diophantus extends basic methods such as those outlined above to problems of higher degrees that can be reduced to a binomial equation of the first- or second-degree. A special case of the decomposition of the product of two sums of squares into other sums of squares see above, Porisms and Lemmas had already appeared in a text from Susa.


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. Although The Porisms is lost, three lemmas contained in The Porisms are known because Diophantus refers to them in Arithmetica. Almost nothing is known about Diophantus’ life.

He is, however, well aware that there are many solutions. Book X presumably Greek Book VI deals with right-angled triangles with rational sides and subject to various further conditions.

The first book, with which exercises II, 1—7, ought to be included, contains determinate problems of the first and second degrees. And the tomb zlexandria scientifically the measure of his life.

Bombelli and Antonio Maria Pazzi prepared a translation of the first five books, but it was not printed. There are two circumstances that from the very beginning hampered or even prevented the achievement of a general solution.
