Hi bobbym

You are thinking of the wrong test.

#1127 Re: Help Me ! » Convergence test of series » 2014-02-20 02:32:36

Nowhere in the statement of the test do I see a condition of the other sequence being smaller... Are you sure you actually opened the link?

Hi Bob

Yey, you are correct,  it cannot be done with less (for the simple reason of 3^4 being smaller than 100 smile).

Hi Vishalini

If you want to be able to measure up all weight between 1 and n, you will need no less than floor(log_3(n))+1 weights.

He has a face. I thought he was a concept.

Oh, yeah, forgot to say that. Compare it to 1/n.

Hi ffd

Agnishom is correct. You can prove it easily by using the Limit comparison test.

"Most cool speech award"? What is that supposed to be?

Congrats on the solved award! smile

Hi vanilla

If you want to check your solution, this is what I'm coming up with:

Doesn't

(up to a period of 2pi)?

From that we get:

I suggest you first change the implications to conjunctions. They are much easier to manipulate.

Hi Bob

You're welcome. smile

For the case in your diagram I get 18/5.

By the way, shouldn't it be "My work"? smile
