Closed form for n-th anti-derivative of $\log x$ There is a typo, you are missing a $\frac{1}{s}$ in $\ln x = \lim\dots$. Don't you need some justification for taking the limit inside though? |

How to find area of triangle from its medians What right triangle? Can you please elaborate? |

Closed form for n-th anti-derivative of $\log x$ You can add an arbitrary $(n-1)^{\text{th}}$ degree polynomial... |

Closed form for n-th anti-derivative of $\log x$ @Argon: Even though I cast a close vote, I now believe it is slightly different, as the $H_n$ term becomes important for $\log x$, but not for $\frac{1}{x}$. |

Using the hypothesis $\frac{1}{a}+\frac{1}{b}+\frac{1}{c}=\frac{1}{a+b+c}$ to prove something else @cruise: I say it is pointless because there is essentially no non-trivial mathematical content there. Anyway, you are entitled to your opinion, as I am mine (and so do the other downvoters/upvoters). I only commented because you seemed interested to know why you got downvotes. I tried to give you the reason why I gave a downvote. Let's leave it at that. It is clear that there won't be an agreement. (btw, you seem to conveniently choose to ignore the 5 downvotes and talk about the solitary upvote you got :-)). |

Using the hypothesis $\frac{1}{a}+\frac{1}{b}+\frac{1}{c}=\frac{1}{a+b+c}$ to prove something else @cruise: I gathered that for the previous comments. But really, the interpretation you chose is quite pointless. |

How to find the limit of these sequences? Oops, cast dupe close vote too quickly. Too many questions in one. The last one is not answered there. |

Binomial Expansion problem error If all you need is verification of correctness, Wolfram Alpha (link computes series $(1+2x)^{1/4})$ is a good resource. |

a system of equation Since we didn't use any inequalities, you can allow the variables to be complex too. |

Iterated function applied on $n/ \log_2 n$ Don't know. Seems difficult. LambertW making an appearance. |

Do there exist functions satisfying $f(x+y)=f(x)+f(y)$ that aren't linear? This has got to be a dupe. |

Proof the sum of the square of the in and out degree are the same btw, the more standard name for a complete directed graph is a tournament graph. |

Proving a trig infinite sum using integration @julien: I think we agree :-) |

Proving a trig infinite sum using integration @julien: Yeah, but Abel's test does indeed prove it (as you mentioned earlier). So there is probably no circularity. I was only trying to clarify. |
