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)

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).

@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

@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.

@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?
