I began to check the mathematics history for some reason. I searched for the historical books of mathematics, visited libraries and bought books. While checking, I found 
as established by Leibnitz in one of these books.
It means that it is Leibnitz that first discovered 
? Then, I am ?-th discoverer of this relation.
It will often happen that if I believe to "discover it" it is wrong or has been discovered by someone else. So, I am not so much disappointed this time.
By the way, when I showed strangers without its proof, they never failed to misunderstandingly say "It can never hold." In other words, where has the Leibnitz's history gone?
