Why is this infinite product for pi not in any textbook? Is it not interesting for some reason?
PI = sqrt(2) * sqrt(3) * 2/sqrt(2^2-1) * 3/sqrt(3^2-1) * ... * p/sqrt(p^2-1) * ...
for all prime numbers p

Why should it be ? What use does it have ? I have no doubt that it is well-know to math nerds who have a special interest in prime numbers, but the rest of us can have a happy, fulfilled life without ever knowing of its existence.
