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

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.

We have some guidelines regarding homework questions: meta.math.stackexchange.com/questions/415/… and meta.math.stackexchange.com/questions/107/…. Disclaimer: Just making sure you are aware of the guidelines regarding homework. Not trying to force you to follow them.

This looks like homework. What have you tried so far? Also, most of us probably don't know "methods covered so far", in your class. Perhaps you would care to state some of the things you are expected to use?

comment Summing something with random and non-random parts
According to mathworld: mathworld.wolfram.com/Erf.html, $erf(x) = 1 - e^{-x^2}(1/x - 2/x^3 + ...)/\sqrt{\pi}$.

@Deb: Yes, better :-) Removed the -1.
