comment How can I solve the 2D Laplace equation with Neumann boundary conditions?
The $n=0$ term is the only one consistent with a constant $x$ derivative at $x=0,L$, but for that term everything is constant and there can be no nonzero derivative at any boundary. I could illustrate the general method, but only for an example that is actually solvable. You would have to edit the question to change the boundary conditions. DSolve is only rarely able to solve PDEs with boundary-conditions - the numerical solvers are able to do that better.

comment Missing tick in plot
@xslittlegrass Thanks for doing that. It's very weird.

I see this too in version 10.1 - has it been reported to Wolfram?

Indeed, you're probably right.

Maybe he wanted the labels the other way around, but the general idea works anyway (+1).

comment Is it possible to export equations from Mathematica to Corel with full Latex quality
@Szabolcs Great, thanks, I'll add that to my linked answer! (I checked that the old syntax also still works in 9.16, though). I'll also have to file another bug report for the Import issue, I guess. Although I believe I reported stuff like that a couple of times already. New issues keep popping up...

comment Custom fonts show as boxes when opening Mathematica-made PDFs with Illustrator
Yes, I think I invented that approach many years ago see e.g. here: Use a custom export function. Here is another relevant link. Also, it seems the ImportString approach is broken because Import now can't import PDF properly anymore. So maybe ghostscript as in one of the mentioned links would be a workaround. But it doesn't really answer your question, of course.

comment Custom fonts show as boxes when opening Mathematica-made PDFs with Illustrator
AArrgh - I just tested the linked approach in version 10.1 and see it's now broken, too. I had been using version 8 until now, and it seems I that was lucky for me. For regular text, it still seems to work, but my example with 2D math is no longer exported correctly. I'll have to look into that, I guess. Why??

comment Custom fonts show as boxes when opening Mathematica-made PDFs with Illustrator
My previous comment won't make sense to most people without a reference: here is what it does: it creates outlines for text glyphs. Then you can export the result, and all text is rendered as vector curves in Illustrator. The TextMode option in the linked answer is no longer needed to make it work (but doesn't hurt, either).

comment Custom fonts show as boxes when opening Mathematica-made PDFs with Illustrator
I long ago stopped worrying about font problems and instead always use this: First@ImportString[ExportString[Graphics[Text[Style["text",FontFamily->"Times"]‌​]],"PDF"],"PDF"]. It's not completely fool-proof with exotic Unicode characters, but usually gives me what I want.
