What questions?

determine if the series is absolutely convergent, conditionally convergent or divergent

1- ∑ (-1) √ln(n) / n

2- sin√n / √n^2+1

Q2) find the interval of convergence abd radius of convergence:

∑ (x-1)^n / n √n

Hi Plato
may you help me to find the answers
Because the Dr. wants to the answer tomorrow

5. ## Re: determine if the series is absolutely convergent, conditionally convergent or div

What have you tried?

6. ## Re: determine if the series is absolutely convergent, conditionally convergent or div

Dr. did not explain the lesson well
It is difficult to me

7. ## Re: determine if the series is absolutely convergent, conditionally convergent or div

So your answer to "What have you tried?" is "Nothing". I think I'll put in as much effort to help you...

8. ## Re: determine if the series is absolutely convergent, conditionally convergent or div

I'm sory
It's difficult form me
I nead fast help

9. ## Re: determine if the series is absolutely convergent, conditionally convergent or div

Thanks time ended Before I get to answer

10. ## Re: determine if the series is absolutely convergent, conditionally convergent or div

And if you'd taken my suggestion, shown some effort and attempted the questions yourself, shown where you were stuck, you would have gotten some help. You have nobody to blame but yourself.

I suggest you read my signature...
