I wonder if there is a nice formula for the pi from n plot (extended to real n-s). It looks "nice enough" on the first glance. As for n=0, can't you prove that

I wonder if there is a nice formula for the pi from n plot (extended to real n-s). It looks "nice enough" on the first glance. As for n=0, can't you prove that pi=inf for n=0 using limits?
