Re: Bafflers?
Hi gAr;
Your welcome, we have a problem on the other question.
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

1) Can you find an a0 that will produce an infinite sequence?
2) An a0 that will produce a finite sequence?
What do you exactly mean by a finite sequence?

Re: Bafflers?
Does the a_n's ever run out of digits? That would be a finite sequence.

Re: Bafflers?
So a sequence of the form:
is finite, right?

Re: Bafflers?
That would be an infinite sequence. A finite one would be one that ran out of digits. Remember a digit is sometimes just dropped! If I show you one it gives the answer away.

New Problem:
How many solutions are there to,
A says)21 solutions.
B says) Nope! That is too high.
C says) I counted them, there are 8.
D says) I like 21 too.
E says) I agree with B.

I have a question for you. Is there a closed form for:

Hi,
I found that it's a theta function, maybe it doesn't have a closed form.

That's nice, is it too hot?
It's supposed to be rainy season here, but no sign of rain!

No rain here and about 110F. Was hoping to be in Florida by now which is more humid and more tropical.
