How do I implement Dynamic Graphics? Somewhat related: Exporting a Video of a Simulation of Pendulum Motion and links therein. |

How do I evaluate several n-th derivatives of a function at one point? BTW, there is another cool use for this method: to prove that the Dirac delta function is the limit of the sinc function, one can do this: InverseFourierTransform[
Limit[
FourierTransform[Sin[\[Omega] t]/(\[Pi] \[Omega]),\[Omega],\[Tau]],
t->\[Infinity]],
\[Tau],\[Omega]] (I actually don't know any better way of getting that result in Mathematica because of the conservative way DiracDelta is defined). |

How do I evaluate several n-th derivatives of a function at one point? This does work, but only if the function decays fast enough to infinity. I don't think it will work for any kind of polynomials. E.g., try x^2: you get indeterminate errors (with n=1). |

Drawing Cylindrical Segment with Graphics3D But this doesn't hide the intersecting caps properly at the branch point, which is the main point of the question. You can see this more clearly by increasing the Tube radius in your example. |

Dynamically labeling a family of curves By "dynamically," do you really mean you want to place the labels programmatically based on the coordinates computed in Table? In Mathematica lingo, "dynamic" placement would usually be interpreted as "interactive" manipulation. |

Error invoking Information on functions containing Legended I agree it behaves like a bug. Would you mind adding the bug tag to the question (so I don't get in trouble for doing it myself)? |

Most CDF displays in browsers suddenly became grayed out Fortunately I don't see any problems in Chrome or Firefox on Mac OS X (10.7.5). Not much help, but at least you know some people still can see your content... |

Error invoking Information on functions containing Legended Unfortunately, your edited solution doesn't work with my original function. And your first solution (using Unprotect) still doesn't work with the function I defined in this answer which motivated my question. But certainly some kind of UpValues solution will be the way to go, even if it has to be more hand-tuned... so I upvoted this. I'll wait a little more before accepting it. |

Error invoking Information on functions containing Legended @Silvia Interesting observation. I have to add that to my question: the function should first be evaluated to see the error. |

rasterListContourPlot With PlotLegends in Mathematica 9 I've changed the code at the URL linked above, so the problem mentioned in the question no longer occurs. If the changes work as I hope, it may be best to close this question as too localized. But I'd suggest waiting a little so I can get feedback. |

rasterListContourPlot With PlotLegends in Mathematica 9 The reason my functions don't work with version 9 legends is of course that they were written before version 9. And unfortunately the new legends cause the output of plots to have different Head (Legended instead of Graphics) when you specify a legend. I didn't anticipate this new invention (nor do I think it's a good change). But I'll try to modify my functions eventually. This kind of thing is exactly why I've mainly kept working with version 8 so far. It's too much work to update all my notebooks... |

A matrix-vector cross product @J.M. BTW, a related answer where I used this is: Is it possible to do vector calculus in Mathematica?. Hope you don't get into an identity crisis... |

Find points on the surface of a Graphics3D object I assume you're aware of this, but the vertex coordinates of the original PolyhedronData object are accessible like this: PolyhedronData["GreatStellatedDodecahedron", "VertexCoordinates"] // N |

Override Equation structure change in mathematica - CopyToLaTeX @Rojo Ah, that could be. I'll wait for clarification. |

Override Equation structure change in mathematica - CopyToLaTeX @JonathanShock I understood it differently. The question is explicitly about TeXForm rearranging things. What you mention already happens in StandardForm. If you're right, the question is phrased incorrectly. |

Exploiting self-adjointness when changing basis This has also been addressed in the comments and answers to Can Eigenvalues and Eigenvectors be assumed to return the same ordering? |

Export matrix to $\LaTeX$ with style A general-purpose way of getting useable $\LaTeX$ code is to Export as PDF, then import into Inkscape and from there choose Save As > LaTeX with PSTricks Macros. That produces a .tex fragment which can go into the body of a host file as long as the latter calls \usepackage{pstricks} first. This isn't specific to tables, it works for anything that can be exported as PDF. For specific things like tables, it's also possible to generate the $\LaTeX$, but only by hand-coding it. |
