comment Am I entering this 2-variable recurrence correctly?
I believe that you are using the correct syntax.

comment Applying TextRecognize on alpha-numerical table
The periodic table must sound very French :P This "tweaking" must have taken you a while to get right

comment Applying TextRecognize on alpha-numerical table
Nice (and got the +1 when you posted), but it's a bit unfortunate that we need to write our OCR engine from scratch (what you practically did here!) because TextRecognize won't allow configuring Tesserract (the engine it uses) with enough flexibility. One important step in your solution is restricting the possible set of characters. Tesserract has options for this, but TextRecognize doesn't expose them.

Did you look at the Filling option of Plot?

comment intersection between two curves in Mathematica
If you need linear interpolation for tabulated values of r, you can do tab = Table[{phi, r[phi]}, {phi, 0, 2 Pi, .1}] to compute tabulated values, then tab = Table[{phi, r[phi]}, {phi, 0, 2 Pi, .1}] to get the interpolating function. Note that this is linear interpolation, i.e. made of line segments (I think that is what you want): tab = Table[{phi, r[phi]}, {phi, 0, 2 Pi, .1}]

comment How can I define a 3D version of the built-in VoronoiDiagram function?
I took a look at the package, and it seems it's not immediately trivial to set it up with the current version of qhull. So I agree with MrW, if anyone gets it working, please describe how to do it. @Tuku did you get it working?

comment How can I define a 3D version of the built-in VoronoiDiagram function?
@Mr.Wizard It's a link to a ready-made package that contains the functionality. The package seems to interface with a mature library, i.e. I expect it to be fast and accurate. I think this is a very useful answer and it leads the way to a solution that is much better than anything with Nearest. Lately I have the feeling that on this site we expect too much. Answers which don't give working code are not upvoted even if they give the key to the solution. The OP should really be able to handle it from here. If I were the OP, I'd focus on this answer first and accept as soon as I got it working.

Interpolation should work. Could you post two example curves to work with?

I did see your deleted answer but I strongly thing that this info should not be left as a volatile (deleted any day) comment

You need to read up on Map.

Actually it does exist in Mathematica, see my answer.

@ruebenko If you post an answer with the precise command, I'll delete this one. I'd have to keep reading the docs for a while to figure out the right syntax.
