Alexei, if this is you, you might want to merge the account you posted this with, with the other account. Please reply to this or flag your post if that's what you want.

comment Alternatives to Mathematica
Since Mathematica.SE is where the users of Mathematica on StackOverflow went, I don't think that is a reason that justifies re-asking of the question. It is possible that five more years has changed the answers, but to be honest I think this question is borderline off-topic. I will leave that judgement to the community, but it is possible that others will agree and put the question on hold.

comment How can I get a result with 12 digits of precision?
Is there a particular reason why you want 12 digits, or is that just because you are trying to find ways to reduce the calculation time? In any case, difficulties solving this particular system is a separate question to the one you asked about how to enforce a particular precision. I did actually answer the one you asked.

comment Are you interested in purchasing David Wagner's “Power programming with Mathematica”?
@Reb.Cabin I hadn't heard from Todd Allen about permission to do so. I will ping him.

comment The guidelines for options or multiple arguments?
Actually, I think this question can be written in a way that doesn't fall out of bounds of the site. See this old question of mine for an example of a "best practices" question that was considered useful and in scope. If you can edit the question a little to read less like you are asking for opinions, then I think it can stay open. Otherwise I will close it.

comment Creating a highly customized BarChart
@GregoryKlopper - yes I did it that way to illustrate the relationship between the coordinates. Sorry for not making that clear.

comment Creating a highly customized BarChart
@GregoryKlopper - I can't respond in detail until this evening (9am here). The BarSpacing documentation says that for BarChart, the spacing is in fractions of widths of a bar; the bars are 1 in width and the first one is centred on 1. That means that the first bar's right edge will always be at 1.5, but the left edge of the next bar depends on OptionValue[BarSpacing]. I think it should be possible to automate your problem but it would be quite a bit of work. Let me think about it for a bit.

comment Normal and Tangent of Acceleration in 3D
@J.Musk - I'd also point out that marking a question is duplicate is not the same as closing it for some problem (e.g. being off-topic). It is not intended as negative feedback. It's a device for saving everyone some time. If your issue has already been answered adequately elsewhere, then you will get quicker resolution by being pointed to that answer than by waiting for someone to come up with another version of the same solution.

comment Normal and Tangent of Acceleration in 3D
@J.Musk - I have reopened your question for the time being. Please understand that people aren't closing questions because they don't feel like answering them; sometimes they can be genuinely misled by confusing terminology, as in this case. Please also understand that everyone here is volunteering their own time to help others with their questions, and it helps us to help you if you provide complete minimum working examples and make some effort to format your post to be legible.

comment How can I get vectorized text when exporting to pdf?
This is not an answer, but the same thing happens when exporting these graphics as EMF or WMF.

comment Does Mathematica have a command analogous to ode45 of MATLAB?
This is nice, but is it a coupled second-order system? I think that would be more helpful to the original poster.

comment How to manipulate a plot with intermediate parameters
Dear lcet, this is your fourth question posted on the site. People are generally finding them hard to follow. It is often not clear what you are wanting. That is one reason you are getting downvotes. The other is that you are dumping large amounts of hard-to-read code in your questions. Please simplify your code to a minimum working example, and use normal letters instead of greek letters for parameters.

comment Having used Mathematica as a “gateway” language, where to from here?
I don't want to close this question, but I would ask that people posting answers address some key issues that would be relevant to Mathematica users: (1) integration with Mathematica; (2) learning curve for someone already familiar with Mathematica and functional programming; (3) value-add of things Mathematica doesn't do so well (o/o, performance etc).

comment Setting OperatorSubstitution to False has issues with PDF and EPS exports. Are these bugs?
Could this be an issue with the font? I can't replicate the PDF export problem on Windows using Verdana, Consolas or Vivaldi: it definitely uses the selected font for operators and the custom Mathematica fonts are not used. And I have never had this problem on my Mac at home. I have Mathematica 9 on both machines. Maybe try Consolas for the time being?

comment from complex function to a series
After tidying up your expression and using FullSimplify on it, I get zero. Is that what you expected?
