Re: Series

Hi anonimnystefy;

gAr is right. I did not get around to helping you with yours but that identity you chose is not true.

I have the result, but I do not yet know how to get it.

i don't know how i got to it then.

Re: Series

hi bobbym

if i'm not mistaken this kind of computing is called telescoping.

Re: Series

Yes, that is correct. The whole idea has been expanded into what has been called "Creative Telescoping."

Re: Series

nice.i would just like the rest of the sums to be solved so that gAr could give out some slightly easier sums.not too easy.just slightly easier.
