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.

Veselovsky, commentary by I. The dating of his activity to the middle of the third century derives exclusively from a letter of Michael Psellus eleventh century. Diophantus uses it in the problems immediately following VII. Only 6 of the 13 books with which he is credited are extant.

And most modern studies conclude that the Greek community coexisted [ Keep Exploring Britannica Thomas Edison. An extant work called Preliminaries to the Geometric Elementswhich has been attributed to Hero of Alexandriahas been studied recently and it is suggested that the attribution to Hero is incorrect, and that the work is actually by Diophantus. Hankel2nd ed. We do not know.

Arithmetica was first translated from Greek into Latin by Bombelli inbut the translation was never published. Second, Diophantus lacked, above all else, a symbol for the general number n.

Articles from Britannica Encyclopedias for elementary and high school students. Similarly, since brackets had not yet been invented, the negative members diophantua to be brought together behind the minus symbol: We find them in Babylonian and Chinese texts, as well as among the Greeks since the Pythagoreans.

According to this definition, the polygonal number. Diophantus later gives the condition for an integer: In this case one aledandria say whether the proposition was proved. Editions of Arithmetica exerted a profound influence on the development of algebra in Europe in the late sixteenth and through the seventeenth and eighteenth centuries.

This puzzle reveals that Diophantus lived to be about 84 years old.

While the alexandra and third problems are stated generally, the assumed knowledge of one solution in the second problem suggests that not every rational number is the sum of two squares. The manuscript can be dated, for it is indicated at the end that it was completed on Friday 3 Safar A.

We welcome suggested improvements to any of our articles. With these preliminaries out of the way, Diophantus proceeds to the problems. One lemma states that the difference of the cubes of two rational numbers is equal to the sum of the alexanxria of two other rational numbers, i. Today, Diophantine analysis is the area of study where integral whole number solutions are sought for equations, and Diophantine equations are polynomial equations with integral coefficients alexandris which only integral solutions are sought.

### Diophantus | Biography & Facts |

According to some historians of mathematics, like Florian Cajori, Diophantus got the first knowledge of algebra from India, [5] although other historians disagree. The Columbia Encyclopedia, 6th ed. Our editors will review what you’ve submitted, and if it meets our criteria, we’ll add it to the article. Other artifices appear in the choice of designated quantities in the exercises.

I have a truly aldxandria proof of this proposition which this margin is too narrow to contain. So some questions you may ask yourself are: Many who have worked on it have divided the problems into groups according to the degree of the determinate and indeterminate equations.

Diophantus also authored a tract “On Polygonal Numbers” and diophanttus collection of propositions called Porisms. Heath stated, “Diophantus evidently put down alexancria equations in the ordinary course of writing, i. Forty—four problems of book IV are discussed by E. It is a collection of problems giving numerical solutions of both determinate and indeterminate equations.

Fermat’s proof was never found, and the problem doophantus finding a proof for the theorem went unsolved for centuries.

Home People Science and Technology Mathematics: There is also the definitive text with Latin translation by P. The editio princeps of Arithmetica was published in by Xylander.

Like many other Greek mathematical treatises, Diophantus was forgotten in Western Europe during the so-called Dark Agessince the study of ancient Greek, and literacy in general, had greatly declined. The symbolism that Diophantus introduced for the first time, and undoubtedly devised himself, provided a short and readily comprehensible means of expressing an equation: He was the first person to use algebraic notation and symbolism.

A prominent German mathematician Hermann Hankel commented that his work is devoid of general method and each problem is solved through a unique method and application of that one method is impractical to other somewhat similar problems.
