Is $\nu_1\perp\nu_2$ equivalent to $|\nu_1|\perp|\nu_2|$ for complex measure? You may want \perp instead of \bot; the spacing is better with \perp. |

Proving the value of a limit using the $\epsilon$-$\delta$ definition I don't think your sarcastic condescension helps anyone. |

Finding $\int_0^{\pi/2} \sin x\,dx$ @Arturo: Yes, but why is the derivative of $\cos(x)$ equal to $-\sin(x)$ when $x$ is measured in radians? |

Finding $\int_0^{\pi/2} \sin x\,dx$ @Isaac, you're right that that does make more sense. I'll change my question (though I'm not sure it was particularly unclear originally). |

Finding $\int_0^{\pi/2} \sin x\,dx$ So you answered why the integrals give different answers scaled by a the ratio between a degree and a radian, but I already knew this. My question was why radians are special and give the answer of 1 (which you skip entirely when you say, "We know that…"). Sorry if my question was unclear. |

Coloring points on an n-gon Perfect, exactly what I was looking for! |

Coloring points on an n-gon Thanks; I'm accepting Qiaochu's answer because it's more complete (and also was a few seconds before yours). |

I want to put my words into a formula/algorithm but I lack the mathematical fortitude I agree with Yuval here; there's no reason to use any fancy math notation because the words you have currently are already very clear. Adding any symbols would unnecessarily complicate the algorithm. (And anyway, I don't think that there is any standard notation for what you want. Probably the best you can do is just write pseudocode for the algorithm, but that's not particularly mathy.) |

Algorithm for generating integer partitions @Will: Are you sure? I think that should work fine; that's what maxval is for. |
