From a list of dates get a list of the last date available in a each month Somehow I had interpreted the question as asking how to determine, in a list of dates split by month, the latest date for each month. But I guess your interpretation's the one. |

From a list of dates get a list of the last date available in a each month You know, you could have done Last /@ (* stuff *) instead of Last[#] & /@ (* stuff *)... otherwise, your method looks perfectly straightforward. |

Can I use Table without the appropriate bounds? @Max: we might be more helpful if you tell us your actual problem, that is, the problem that requires this construction you speak of. |

Calculating a limit with a result that is discontinuous in the parameters It's a bit too specific (that is, unless I see multiple Limit[]-related questions cropping up, I don't see the need); at the moment, calculus-and-analysis is sufficient to cover your question. |

Calculating a limit with a result that is discontinuous in the parameters Yes, that's why I only posted a comment as opposed to an answer. Note that both HeavisideTheta[] and UnitStep[] have a different definition from your $\theta(u)$; your limit evaluates to $\dfrac12$ for $\varepsilon=0$, for instance. |

Calculating a limit with a result that is discontinuous in the parameters The thing here is that Mathematica always thinks that variables take on complex values, unless told otherwise (via, say, Assuming[] or the Assumptions option)... |

How do I slice an image of size “width × height” in n² pieces of size “width / n × height / n”? @bel: more precisely, I made use of her picture already as an answer to another image-related question... |

Sorting a list and finding an array of indices that sorts the list @Rojo: that's a good point with respect to saving sorting effort. :) |

Creating a Sierpinski gasket with the missing triangles filled in @R.M: I didn't realize until now that the third argument of Scale[] was crucial here so that we don't have to futz with the PlotRange... |
