comment Mathematics in the Classroom
"too audienced towards someone who has some desire to learn as opposed to math-illiterates". Well you cannot teach anyone who does not have the desire unless they are really small kids and you are forcing them. Even then how effective the solution is, I am not sure, but it is surely not fun then. :P

@joriki yes, I rewrote the sentence. I hope this formulates my problem better.

comment Compute $\lim_{n\to\infty}(n-(\arccos(1/n)+\cdots+\arccos(n/n)))$
That the error part decreases as $1/N^2$ is decisive for the proof. Nice. :-)

comment Information on the sum $\sum_{n=1}^\infty \frac{\log n}{n!}$
@did Sorry, you misunderstood me. I wanted to ask the reason for your comment "What is the meaning of "play with formulas equivalent to the original question and bringing no new information nor understanding to it"? "

comment Information on the sum $\sum_{n=1}^\infty \frac{\log n}{n!}$
@did Complete noob here. So may I ask you to explain why the two formulas are equivalent? I have got a suspicion it is so because it is basically just replacing formulas with numbers? Am I correct? For example, is this similar to saying that $\sum_{n=0}^\infty \frac{1}{n!} = e$?

This is how I did the problem the first time, but then I forgot how I did it and was stuck. :P Thanks :-)
