This 12 year-old is asked to prove the convergence of the following...

Just looking at this.. since sin and cos vary between -1 and 1 there doesn't seem to be any way for this series to converge.

Any thoughts?

You are right, it's a periodic function, hence does not converge.

Hi Fruityloop;

I do not believe that converges.

I also do not like him using the integral test which is only for series with positive terms that are monotone decreasing. This series does not apply.

Please take a look at these comments from one of the geniuses that come in here everyday.

What a charming little tyke. Isn't he adorable?

I noticed his IQ was higher than yours m.

I sure wished they had let him go on trying to prove that sum is convergent

He certainly is a busy little guy. You can not have a swollen melon.

Yea, but I am better looking.

Why should that count?

It does not count. I was making a little joke and perhaps responding to the comment.

And funny too, don't you think?

Did you watch the video of Jake?

No.

I'm actually confused about the whole thread

The fact is Jacob Barnett is a fake, immature, glory-seeking and spoiled child.

I thought his parents were kind of smug.

Look at this: now the wikipedia page identifies Barnett as a child prodigy.
