I am a mathematician by profession and quite a long-time (since around 1995 – as of now [2014], this means more than 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 am a heavy Emacs user, though still a newbie – I started in 2001.

I have a blog about (among others) TeX and friends, located at http://mbork.pl/Content_AND_Presentation.

comment 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.

comment 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.)

Thanks! I just discovered With myself, too, but I've put it inside Show; I guess this doesn't make much difference.

Interesting. Why do you provide two rules for fx[x_,y_]?

comment 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.

Exactly, I just thought there's another way.

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?)

comment 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?
