Leonardo Fibonacci or Leonardo of Pisa ( 1170-1240 ) is an Italian mathematician who works on mathematical cognition of classical. Arabic and Indian civilization. He made some parts in the field of algebra and figure theory. He went to Algeria and continues to larn and add more cognition. The plants of Fibonacci exist which he wrote in the field of figure theory. practical jobs in concern mathematics and surveying and some recreational math. Such of these are the summing up of recurrent series called the Fibonacci series. Each of these series is called the Fibonacci Numbers- the amount of two predating it in series. He was awarded a annually salary by the democracy of Pisa in 1240 bespeaking the importance of his work in different field of mathematics and besides in the public service.
The Fibonacci Numberss are 0. 1. 1. 2. 3. 5. 8. 13…The expanded value of the sequence in an illustration of a recursive sequence which is obeying the regulation that to cipher the following term one merely the amount of the predating two: therefore 1 and1 are 2. 1 and 2 are 3. 2 and 3 are 5 and so on. These simple forms are apparently singular recursive. which fascinated by mathematician for the past centuries. Its belongingss show an array of surprising subjects and new finds from aesthetic philosophies of ancient Greeks to the growing forms of workss ( non advert the population of rabbits. )
Some of the graphics that is included in the utile find of the sequence is “The Ahmes Papyrus of Egypt” which gives an history of constructing the “ Great Pyramid of Giaz in 4700BC with the proportions harmonizing to a “Sacred Ratio” . The Parthenon. which sculptured by Phidias. The Mona Lisa by Leonardo Da Vinci. This believed that Leonardo as mathematician tried to integrate of mathematics into art. This picture seems to be made intentionally line up with aureate rectangle.
The mathematical form of Fibonacci Numberss can be determine in the Pascal’s trigon utilizing the Fibonacci series to bring forth all the right angle trigon with whole numbers sides based on Pythagoras theorem.
The aureate Section
The aureate subdivision of Numberss are ± 0. 6180339887…and ± 1. 6180339887…this aureate subdivision is besides called the aureate ratio. the aureate mean and the godly proportion. The value of this is ( 1+ sqrt5 ) /2. It can be describe by the form of the Fibonacci sequence. The consequence of this ration x1= 1/1. x2 = 2/1 … Xn= degree Fahrenheit ( n+1 ) /f ( n ) so utilizing the recursive form. This equation for work outing for ten is truly a quadratic equation and is positive root. They believe that this ratio was the most perfect proportion.
We can besides depict the aureate subdivision by utilizing the aureate rectangle. The procedure is by taking the squares with the sides whose length correspond to the term of the sequence. and set up them externally spiraling” form. The consequence at each phase are approximately the same portion and that. the ratio of the length to with seems to settle down as we build the form outward. The ratio of the length and the breadth is at every stairss the ratio of the two consecutive footings of the Fibonacci sequence. that is the ratio of the greater one to lesser.
It is said that the growing of this nautilus shell like the growing of the populations and as many sorts of natural turning and by somehow governed by mathematical belongingss. exhibited by Fibonacci sequence and that non merely the rate of growing but the form of growing.
