How to determine all cases consistent with constraints @JonathanShock: Both of the conjunctions I showed (in In[1] and In[2]) are tautologically False, irrespective of the truth value of the individual components. |

Symbolic derivative of $n$-term product @whuber: I've added a clarification to my post. |

Symbolic derivative of $n$-term product @DanielLichtblau: Thanks! This is probably the road to the proof I'm looking for, even though, as you say, it does not use Mathematica much. (See my comment to whuber's answer.) |

Symbolic derivative of $n$-term product Thanks! I picked your answer reluctantly, because I really would have preferred to pick all three: each shows something different and valuable. I figured that it would be better to choose (however inaccurately) than not to, so I finally went with yours on the grounds that it contains most Mathematica-specific stuff... |

Symbolic derivative of $n$-term product @DanielLichtblau Actually, this condition is easy to see from the expression for the derivative when $n=1$, so maybe I can set up an induction.. |

Symbolic derivative of $n$-term product @DanielLichtblau: Yes, that's my guess too. |

How to translate interactive graphics from Mathematica to standard HTML+SVG? Even if CDF weren't a proprietary technology belonging to WRI (in contrast, e.g., to HTML + SVG), the fact that, AFAIK, it requires downloading and installing a separate viewer is a deal-breaker for the type of use cases I'm interested in at the moment. I confess that I don't know much about webMathematica, except that using it requires giving WRI more money... (I gave up trying to get the straight scoop on webMathematica after following one-too-many hyperlink to a sales-hype-filled page.) |

How to translate interactive graphics from Mathematica to standard HTML+SVG? @cormullion: I can't come up with a quick and non-controversial answer to your question... :) |

What algorithm does Plot use to determine abscissas? @Mr.Wizard: That link leads to quite a lode of insight on Plot's ways... Thanks! |

How to translate interactive graphics from Mathematica to standard HTML+SVG? I don't know much about SVG yet, but my impressions about it so far are consistent with your comments. Namely, SVG provides the graphics primitives, but there do not seem be any decent libraries (in JavaScript or anything else) to support higher-level programming of SVG-based plots. |

How to translate interactive graphics from Mathematica to standard HTML+SVG? "Whatever your approach, you'd certainly need a good library of special functions and tools to solve equations involving these over entire intervals" Well, a point to such a library was one of the types of answers I was hoping for... Thanks for the nice example, BTW! |

What algorithm does Plot use to determine abscissas? @belisarius: Yeah, that's what I was alluding to with my opening parenthetical remark... Your comment basically tells me that, yep, my question was pretty naive... I guess I was hoping to find something like "Mathematica's algorithm is based on a fourth-order Craske-Trump adaptive bisection algorithm, but it has been enhanced with many proprietary modifications..." |

What algorithm does Plot use to determine abscissas? @belisarius: interesting trick, thanks, but I confess that I don't feel much more capable of guessing Mathematica's algorithm for generating the mesh than I was before... |

How to translate interactive graphics from Mathematica to standard HTML+SVG? @Ajasja: That's precisely one of the options I was trying to exclude with the "non-propietary" qualifier... |

How to automate x[i]→x_{i}? Your answer suggests that Mathematica itself can render TeX. Can it? |

How to combine ArrayPlots? Thanks for your post and comments. (The latest version of your post makes my previous comment invalid, so I've deleted.) |

Is it possible to specify a context-sensitive, “depth-agnostic” rewrite rule? @LeonidShifrin: Thanks! |

Is it possible to specify a context-sensitive, “depth-agnostic” rewrite rule? ++Thanks! This goes a long way. Minor follow-up comment/question: for RR1-RR3, it looks to me like, for the innermost replacement, Rule may be used instead of RuleDelayed... I haven't yet come up with a case that would distinguish a clear preference for one (of Rule vs RuleDelayed) over the other. |

PDF exports of ArrayPlot's are fuzzy (OS X) @rm-rf: Thanks! If you post your comment, I'll by happy to accept it. |

PDF exports of ArrayPlot's are fuzzy (OS X) @J.M. Yes, same problem. The only difference this time is that, when this second PDF is displayed at "Actual Size" magnification, the plot has the same size as it does in the Mathematica GUI. |
