Homework Equations
comparison test
alternating series test
The Attempt at a Solution
I know the limit of this is zero and it's decreasing so it's either conditionally or absolutely convergent, but I do not know what test to use so...
No, I haven't heard of any of those.
I used the limit comparison test on the two series sqrt(2n)/sqrt(2n+3) which equals to one. Doesn't that prove they are both divergent because the limit is greater than 0 due to the limit comparison test?
Homework Statement
The equation is the summation from n=1 to infinity of [(-1)^n] / [sqrt(2n+3)].
Homework Equations
If the series An is compared to a a series Bn that diverges and the series An is greater than the series Bn they both diverge.
If the limit from n to infinity of...
