I am a mathematician by profession and quite a long-time (since around 1995 - as of now [2012], this means almost half of my life) TeX user by hobby.
I started with plain TeX, and much later (in the early 2000s) moved to LaTeX; I still use plain TeX occasionally (and when writing LaTeX classes/packages). Quite recently I also started to use ConTeXt.
I have a blog about (among others) TeX and friends, located at http://mbork.pl/Content_AND_Presentation.

How to approximate a given WAV file with trigonometric series? Thanks! Is it possible to export this as a WAV file? I did try Export["file.wav",...], whith various things as ... (i.e., Sound[...], SampledSoundList[...], ...), but didn't succeed. |

What does Clear[Evaluate[Context[] <> “*”]] mean? @rm-rf: no, it's fine - you were right, I just didn't do my homework. |

What does Clear[Evaluate[Context[] <> “*”]] mean? Wolfram Demonstrations are too complicated, I guess mostly because of (impressive, I have to say) eye-candy. I'd like to see either a 100+ pages' tutorial on main concepts, or a set of easy-then-harder-and-harder examples. (I might even want to write one some day;).) |

What does Clear[Evaluate[Context[] <> “*”]] mean? Well, I do understand that. I admit that Mathematica is not similar to many other things, and I guess this contributes to the steep learning curve: I don't have a good mental model of how it works. (Well, I can see some similarities to Lisp, of course, and even to TeX, which - as a programming language - is even more esoteric, but has e.g. a similar notion of "expansion" (called "evaluation" in Mma); still, Mma seems to be very different. What would help is a tutorial giving some kind of broad landscape. L. Shifrin's book is very nice, but too comprehensive for that; |

What does Clear[Evaluate[Context[] <> “*”]] mean? I see, I was just RTFM'ed;). Guess you're right; however, the notion of "context" wasn't, well, explained by the docs (now I found the tutorial on contexts, that is much better). As a long-time TeXnician and a boardgamer, I do understand and appreciate the existence of a learning curve for any sufficiently advanced/powerful system - it's just that in the case of my Mathematica "project" I struggle against a deadline... |

How to speed up drawing a tangent plane? OK, thanks. For the moment I thought that somehow the Limit one is chosen if the D doesn't work (e.g., when the function is given by a separate rule for one point). And thanks for the nicety - the large point! (I did it using a one-element list in ListPointPlot3D, definitely less elegant.) |

How to speed up drawing a tangent plane? Thanks! I just discovered With myself, too, but I've put it inside Show; I guess this doesn't make much difference. |

How to speed up drawing a tangent plane? Interesting. Why do you provide two rules for fx[x_,y_]? |

Are there any offline tutorials for Mathematica? Well... 70 EUR - waaay above my price range. I'd pay, say up to 10 USD; this price looks more like a joke for me. Of course, with 1200+pages it might be fair, but I guess 80% of those pages would be of no use to me. Anyway, thanks. |

How to find (numerical) value of a derivative at point? Exactly, I just thought there's another way. |

Are there any offline tutorials for Mathematica? Nope, thanks! BTW: thank you for your book on Mma programming, I already have it on my Kindle and have read quite a bit! (And could you make this an answer, so that I can accept it?) |

How to find (numerical) value of a derivative at point? Thanks, but formally, this is the limit of the derivative as the point tends to zero, not exactly the derivative at zero (though in this case they are equal). Do I have to resort to Limit and the definition of a derivative to do it in the general case? |
