    Don't have an answer, but I'll note 2 findings given the hint: 1) 505 is the hypotenuse of a triangle with integer length sides. 2) Rot13-ing the Roman Numerals for the number 105 produces a trigonometric term. Maybe one of these is on the right path and will help someone.

Reasoning




In Roman numerals 505 is DV. If we use rot13 on these two characters, we get QI.
Qi is the circulating life force whose existence and properties are the basis of much Chinese philosophy and medicine. It allows us to say that we are one with the universe. In this way, 505=1

By using




hexomino's idea of ROT13 on Roman numerals




we can obtain




$text{ROT13}(505)=text{ROT13}(V^4-V^3+V)=I^4-I^3+I=1$.

    $begingroup$


    The rot13 translation of "one" is "bar". The only connection between "bar" and 505 that I could find is this very obscure definition given in urban dictionary (which was entry #4 and has more downvotes than upvotes), which says that it's slang for getting a drink at a bar with friends after work. Perhaps it's a really old outdated slang term, which is why your grandpa used it.

      Elaborating on @hexomino answer 505 -> DV.




      Is it possible that:




      I want to DownVote you 505 times which was odd number resulting 1 DV.
      var num=505; isOdd(num); function isOdd(num) { return num % 2;}

      I'm not downvoting you.

                        Elaborating on @hexomino answer 505 -> DV.




                        Is it possible that:




                        I want to DownVote you 505 times which was odd number resulting 1 DV.
                        var num=505; isOdd(num); function isOdd(num) { return num % 2;}

                        I'm not downvoting you.

                                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...
