Re: Limits!

How about playing with some numbers?


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: Limits!

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

Try good ole substitution.

Re: Limits!

substitution with what? Gamma(n+1)?

Re: Limits!

How about using one of the most advanced techniques ever discovered. Totally unknown to modern mathematicians.

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.

I bet you plugged in nothing but even numbers. Try an odd number...

Re: Limits!

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

Re: Limits!

that's what i meant. big_smile

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.

I thought there was another term involving the Gamma function that you left out.

Re: Limits!

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



I do not remember how that was done.
