hello,

based on the formular for Fibonacci numbers I am supposed to calculate the value for the golden section phi.

(1) rn = Fn+1 / Fn converges against phi, and I have to prove that

(2) rn+1 = 1 + 1 / rn and thus phi = 1 + 1 / phi

But how do I get from (1) to (2) ?

any help greatly appreciated!
