Hi,

But the Cassini's identity is

Making use of this may be difficult here.

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.


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Hi anonimnystefy;

That is okay. As long as you saw the method we used.

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."
