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
