## Alternating Series - does not evaulate ....

Maple
All I have a simple Alternating Series - that will not come up with a convergent result in Maple 11. Here is the problem ... Is ... this alternating series convergent or not ? sum((-1)^n/ln(n), n = 2 .. infinity) Application of the Alternating series test says YES ... but Maple does not give a result. Thanks,

LINK to example file with Alternating Series test showing convergent test to be positive.

## Simple Infintite Series - Issue - Direct...

Maple
So I get this to calculate correctly: sum(1/n, n = 2 .. infinity); And the result is infinity - which is obviously correct. but the following does not give me a result ... sum(1/ln(n), n = 2 .. infinity); what is the trick - do i need to assume something here ? thanks, dp

## Summation peculiarity ... and partial fr...

Maple
hello all ... peculiar problem here ... please help the expression is true that 1/n(n+1) = 1/n-1/(n+1) since 1 = n + 1 - n gives 1/n = (n+1)/n - 1 Is there a way to demonstrate this identity in Maple ? ? I cant find any trick with "expand" or such that works. This impact is also seen when evaluating ... the following ... sum(1/n-1/(n+1), n = 1 .. infinity) = 1; = print(`output redirected...`); i get the proper answer of 1 but no answer with :::
