Fibonacci Squares Math
Fibonacci numbers appear unexpectedly often in mathematics so much so that there is an entire journal dedicated to their study the fibonacci quarterly.
Fibonacci squares math. Ln y2 2 x2. When hearing the name we are most likely to think of the fibonacci sequence and perhaps leonardo s problem about rabbits that began the sequence s rich history. Fibonacci sequence makes a spiral. Since we add the square 9 to the first sum in order to get the second we have 16 9 25 as a sum of two squares adding to a third square.
Do you see how the squares fit neatly together. For example 5 and 8 make 13 8 and 13 make 21 and so on. And here is a surprise. Fibonacci is one of the best known names in mathematics and yet leonardo of pisa the name by which he actually referred to himself is in a way underappreciated as a mathematician.
Applications of fibonacci numbers include computer algorithms such as the fibonacci search technique and the fibonacci heap data structure and graphs called fibonacci cubes used for interconnecting parallel and distributed systems. If n is even 3 gives. Thus the sums 1 3 5 7 16 and 1 3 5 7 9 25 are both squares. So term number 6 is called x6.
If n 1 mod 4 then l1 1 whereas if n 1 we can write n 1 2 3 r k where k has the required properties and then obtain by 11 ln l1 1 mod lk and so ln x2 since 1 is a non residue of lk by 10.
