comment Looking for a certain math symbol
I upvoted your answer. Even better to use the \ang command from the siunitx package.

comment TikZ: Parametric Gnuplot plot fails to appear
As Joseph stated, the "original sin" (in the true sense of the word) is in the OPs code. I looked to the picture and didn't realize that the error was in the question.

You are absolutely right. I started from the picture...

Found the error: x=t+2sin(2t) and not x=t+2sin(t)

comment TikZ: Parametric Gnuplot plot fails to appear
There's something wrong with the evaluation of the function. For instance, if t=-6.22, x=-5.97 and that's right. But if t=-4, x=-5.98 and we see that the graph of the function is wrong because your curve is simple near x=-6 while the original one is not (see the picture in the question).

I filed a bug report in the support section.

comment Looking for a certain math symbol
@Werner, I don't think this question is a duplicate: it hasn't been asked before and hasn't an answer yet. Yes, it's true that one of the answers to the other question leads to the answer for this one, but this question is not about searching for any symbol. Otherwise, every question that has an answer in the documentation of any package should be marked as duplicate.

@danzibr it means 6[cos(200°)+i sin(200°)]-4[cos(50°)+i sin(50°)]=-8.21-5.12i

comment About the actual meaning of \pgfplotsunitxlength macro from the pgfplots package
@percusse you can see that the multiplicative factor is not proportional to the axis length by setting ymax=20. Than you'll see that, until ymax is less than 100, the factor is still 10.

comment About the actual meaning of \pgfplotsunitxlength macro from the pgfplots package
@percusse I understand what you are saying but I think it should be obvious because, as the size of the plot is the same and the axis length changes, the unit vector length will change accordingly. So why relate this macro to the axis length?

comment Draw arrows ending at half circle
What about starting the arrows from the circle using polar coordinates?

comment Is it possible to change the size of an arrowhead in TikZ/PGF?
@DanStahlke, you're right but the code you're using is now superseded. You'd better use the link in the "Update 2013-01-23" section, where that bug has been corrected. Anyway I suggest you to have a look at the new arrows.meta library from the latest version of TikZ, which is an official library.

comment TikZ 3 space between options and named angle in a label no more allowed
@Adam never mind! Maybe that comment was a bit misleading.

comment TikZ 3 space between options and named angle in a label no more allowed
@Adam you are wrong. Please test the code by yourself before suggesting to close it as off topic. There is actually an issue. I forgot to include a particular element in the MWE only, but I fixed it almost one month ago. Please, give it a try and let me know if it works or not (you have to uncomment the first coordinate to see the wrong behaviour).

comment Using opacity in TikZ makes the entire page become “more coarse” when printed
@Daniel, I solved the problem as explained in sec. 9.3 (MS Windows) of Ghostscript manual: When passing options to ghostcript through a batch file wrapper such as ps2pdf.bat you need to substitute '#' for '=' as the separator between options and their arguments. Thank you very much.

@Daniel, I tried with -dPDFSETTINGS=/prepress but the option seems simply to be ignored. The output is always the same (72 dpi) whatever value I set.
