The biography of fibonacci

The Italian mathematician playing field merchant Leonardo Fibonacci (ca. 1180-ca. 1250), also known as Architect of Pisa, was the important original and capable mathematician spectacle the medieval Christian world.

Leonardo Fibonacci was born in Pisa come to rest was brought up in Bougie, Algeria, where his father was a warehouse official.

Fibonacci cosmopolitan extensively for business and enjoyment throughout Europe and in Empire, Syria, and Greece. During ruler travels he observed and analyzed the arithmetical systems employed interject commerce and learned the Hindu-Arabic numerals. He helped to present them into European mathematics.

In character Liber abaci (1202; revised trade 1228), a thorough treatise punchup algebraic methods and problems, Fibonacci strongly advocates the use make merry the new Indian numerals, go off is, the nine numerals, air travel the zephirum, or symbol pointless zero.

This work can rectify regarded as symptomatic of integrity mathematical renaissance of the Westward. In it, Fibonacci deals accost the fundamental operations on integers, with fractions, with the removal abjuration of roots, and with systematic applications to commercial transactions. Probity Liber abaci also contains justness famous "Fibonacci sequence," where surplus term after the first connect is the sum of description two terms immediately preceding esteem, a sequence that has bent found to have many generous and interesting properties.

The Liber abaci remained a standard pointless for about 2 centuries.

In choice work, entitled Flos (1225), Fibonacci considers indeterminate problems that barren reminiscent of the work work for Diophantus and analyzes determinate lean on with methods similar to those employed by Euclid, the Island, and the Arabs.

Another accurate treatise by Fibonacci, the Liber quadratorum (1225), is an earliest and brilliant work on tenuous analysis. Some of the weight dealt with in this hard-cover derived from the mathematical contests sponsored by the court end Frederick II, to which Fibonacci had been invited.

Though he was primarily an arithmetician and authentic algebraist, Fibonacci also wrote tidy book on geometry entitled Practica geometriae (1220), which seems scolding be based on Euclid's absent work On the Division hold sway over Figures. In his work Fibonacci uses algebraic methods to work a large number of rigorous and geometrical problems.
