Fibonacci - so many formulas, so few time ...

 

Given that its not a Mathcad questions and probably also can't be done/proven with Mathcad, I guess chances are rather low that anyone will present a formal proof here.

 

Maybe you find here

and/or in the reference section at the end something of interest.
