Math.SE seems to be going the stackoverflow way. Pity.

@Derek: Please stop editing! I think I fixed it :-) (See revision 4 or 6)

There seems to be a bug/feature! when dealing with <. Probably confusion with html tags. Sivaram, please use \log n instead of just logn.

Even if the derivatives were positive: f(n) = g(n) = 3/2 - 1/10n.

Yeah, just nitpicking :-)

Don't you first need to show $\sqrt[n]{a} \le 1$?

comment Convergence/Divergence of $\sum_{n=1}^{\infty} \sin(1/n)$
btw, the old title said Calc II (I had edited the title to make it more descriptive)! I forgot. I have added the old title to the question body.

comment Convergence/Divergence of $\sum_{n=1}^{\infty} \sin(1/n)$
The user just fired the question and left (typical of people who aren't really interested in learning). So we didn't get a chance to clarify. But the statement: "using methods covered so far" should make that clear I suppose. I suggest you edit your answer only if you agree with the guidelines.
