Re: Limits!

I thought it was kind of artificial. Anyway, it did not stick in my head.


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 a proof is a proof,although i don't like proofs with the use of computers.

Re: Limits!

Hi gAr and anonimnystefy;

We can now use the fact that all the terms are positive except for (-1)^n which oscillates. We just need to prove it does not get smaller.

It is difficult to do in the classical way, but maybe there is something else...
