try the limit comparison test with the known convergent series
Hi,
I tried using the ratio test (ended up with 1 so wasn't helpful), similarly the nth root test and integral comparison test didn't work.
Can I say that:
frac{n+2}{n^3 +1} \leq \frac{1}{n^2}" alt="\frac{n+2}{n^3 +1} \leq \frac{1}{n^2}" />
and 1/n^2 converges by the integral comparison test, so by the comparison theorem, the sum converges?
Is the above correct? Thanks
edit: I couldn't get the Latex to work so I've taken off the tags, sorry!
Thanks for the help. That's what I did, I just wasn't sure if it was right. Thank you!
When I put the tags around it comes up like this
edit: it's working now! but I literally just copied and pasted form my original post! I'll try again.
