comment TikZ, passing two values as an ordered pair
@MarkWibrow, this is exactly what I was looking for. Please write down your answer.

comment TikZ, passing two values as an ordered pair
Because the value is an ordered couple of values, not just a single value and I want to work with the two values separately elsewhere.

I've added a new post in the bug section. I'm copying its content at the bottom of the question to let the other users to contribute the discussion.

comment pgfplots, TikZ interoperability and axis equal
If it can be helpful, I've added a further example in the pgf language in which I've set no local coordinate system and I've used 3D coordinates instead of a 2D ones.

comment Prevent expression evaluation for some values in TikZ
@jfbu, I'm sorry: I mistook the order of the two expressions. Your answer works good too.

comment Prevent expression evaluation for some values in TikZ
No. It isn't a dimension too large error but a division by zero error that is just what I wanted to avoid when I asked to prevent the function from being evaluated in x=0. If I use the @Kpym code substituting the < sign with the = one, it still works good.

comment Prevent expression evaluation for some values in TikZ
I'm trying to modify your function to work with an equal sign but it fails in x=0 like in the question. Is there any way to let it work with the equal sign?

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).

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

@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.
