A. Use ratio test.

B. What about the function ?

C. What have you done? - Apr 29th 2012, 10:36 AMmanholeRe: Series Converges
You in Leache's class?

hahah

Anyway, for A domain should be infinity.

I haven't found an answer for B (could be neither)

and for C http://www.math.sunysb.edu/~disconzi...ging_index.pdf - Apr 29th 2012, 03:42 PMJC05Re: Series Converges
AHHH HAHA

THANKS This problem is killing me....
