Find the square root of n












0












$begingroup$


The task:




Given a real number n, find the square root of n. For example, given n
= 9, return 3.




My solution:



const findRoot = n => n >=  0 ? n ** .5 : void 0;



console.log(findRoot(9));


Is this some kind of trick question? What's there to solve? Did I miss something?

    -1 is a real number. You might also be meant to solve it without using sqrt or floating-point exponentiation.

Is this a new Fibonacci Identity?

Image
6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w
