Talk:Fibonacci polynomials

Closed Form

This is something I discovered on my own a while back, but was unable to find much info about it online. I strongly believe that it is the closed form of the Fibonacci polynomials. I arrived at it by manipulating Binet's formula with the golden function.

I used the Wikipedia math generator to create an image for a school paper, and figured it would be a dumb idea to let the code to go to waste, so here it is:

F_{n}\left(x\right)={{gold(n)^{x}-(n-gold(n))^{x}} \over {\sqrt {n^{2}+4}}}={{gold(n)^{x}-(-gold(n))^{-x}} \over {\sqrt {n^{2}+4}}}\

Again, I have no sources to verify/mathematically prove this, so I'm just posting it here instead. Enjoy!

the summation on the left hand side for the generating functions are over m, while inside the sum they are over n. I think this is a mistake. I can't think how it could possibly be correct! —Preceding unsigned comment added by 121.45.141.190 (talk) 13:30, 21 August 2008 (UTC)[reply]

Formula in Definition

Has anybody noticed that the case for $n=2$ actually agrees with the case for $n\geq 3$ ? I'll modify the formula to reflect this; if anyone has any qualms, feel free to address them here. --JB Adder | Talk 01:11, 23 September 2008 (UTC)[reply]

Please write legibly

The degree of F_n is n-1.

The degree of F_n is n − 1.

I found the first form above in this article. Notice that:

A hyphen does not look like a minus sign; and
Proper spacing should be used.
