does wolfram find when things diverge or converge?

Question

lgbasallote · Answer

depends...are you talking about derivatives or integrals?

anonymous · Answer

for example something like $$\Sigma (4/7)^-k$$

anonymous · Answer

that is supposed to be to the ^-k power sorry not times -k

anonymous · Answer

actually it does

uhh...glad to have helped you answer your own question?

anonymous · Answer

can you find out if it has absolute or conditional convergence?

lgbasallote · Answer

i have a feeling you'll get to answer that on your own too....

kainui · Answer

I think if you type into wolfram "Convergence of Sum from 0 to infinity of (x^x)/x! or whatever, you'll get an answer. Just play around with it a little first and tell us what happens.

anonymous · Answer

alrighty

anonymous · Answer

i dont know if it can do it

kainui · Answer

anonymous · Answer

yaeh i got that to work but how about absolute convergence or conditional convergence

kainui · Answer

I found this thread that's 3 months old, might help http://openstudy.com/study#/updates/4f98eb03e4b000ae9ece8bad

kainui · Answer

I think you're just going to have to know what tests to do for abs/cond convergence and make wolfram carry out the tests themselves.

anonymous · Answer

oh true thanks

kainui · Answer

Yep no problem glad I could help =D

anonymous · Answer

do you know what tests show abs convergence
