Re: Limits!
well i know that Gamma(1/2) is sqrt(pi) but i don't know how that would help.

Re: Limits!
Yes! A fantastic answer. Brilliant in every sense of the word. I love it. It is the same answer I got so long ago!
Unfortunately it is wrong.

The limit does not exist because we do not know what the parity of infinity is.

Re: Limits!
that's what i meant.
but is there a way to prove it other than just trying out numbers?

Re: Limits!
well i think that if we prove that Gamma(1/2-n) has different signs when the parity of n changes,the non-existence is just a consequence.

yeah,you're right.but if we can prove that,than the limit won't exist.

There is one demonstration shown to me where the problem is reduced to
