comment How do we solve third order nonlinear differential equation f’’’+ff’-f’2-Re2 f’=0
You can start with DSolve. If that fails, then try NDSolve.

comment How to differentiate between formatted and unformatted strings?
@rasher thanks, I see it now. But for me it is just a string. Anything with a starting " and ending " is a string. But I understand now the OP wanted to parse/detect it to see if it it contains Mathematica specific content. Ok.

comment How to differentiate between formatted and unformatted strings?
@rasher, ok, I just never heard or seen something called "internally formatted string" reading Mathematica documentation. I just googled this and it turned no hit. But may be I just need to look harder.

comment How to differentiate between formatted and unformatted strings?
what is "internally formatted string"? A string is a string. Why would it matter what is inside it? I did not know that Mathematica had 2 kinds of strings before.

comment FrameTicks and Ticks on Axes in Same Plot
I assumed they wanted on the lower x-axis the same ticks as the top axis (i.e more ticks), but in addition to add those 2 edges special tick labels they had. (you are right, it would have been better to have xt[t] there also). may be OP can clarify.

comment FrameTicks and Ticks on Axes in Same Plot
I understand that what you wanted, but when Frame->True then Ticks is ignored and not even looked at. So there is no point of even having it there. That is what I mean. Try Plot[Sin[x], {x, -Pi, Pi}, Frame -> True, Ticks -> {{1, 1}}] so the actual ticks will have to come from FrameTicks which you already specified.

comment FrameTicks and Ticks on Axes in Same Plot
Since you said Frome->True then you need to use just FrameTicks not Ticks.

@enzotib it a secret option :) I am sure it is there somewhere, but need more time to find it now.

comment Returning a value from a Module
@enzotib Let me reboot my version 2.2 of Mathematica and see. I can't answer this question right now. I would think it always worked this way in Mathematica, but I do not know. May be someone else would. But I will check 2.2 to see.

@ubpdqn lets hope in V 10 they made it more easy to change the tick labels !

Chop[%] gives {{1., 0, 0}, {0, 0.65, 0}, {0, 0, 0.55}} floating point calculation noise.
