comment Exporting combined data plots as a PDF file
What trouble are you having? Did you use the Export command? What did you type? What error did you get? For additional information reference.wolfram.com/mathematica/howto/ExportToPDF.html and reference.wolfram.com/mathematica/ref/format/PDF.html

comment Find maximum from NDSolve output
Well, you can't use NDSolve if you do not have a numerical value for d and T. So, once these are set, and you get your solution xx[t] from NDSolve, then you can use many of Mathematica maximum related functions, may be NMaxValue migth do it. "gives the maximum value of f with respect to x." reference.wolfram.com/mathematica/ref/NMaxValue.html

comment What is the most convenient way to read definitions of in-memory symbols when we don't have the source files? (Spelunking tools)
Great stuff Leonid! would you happen to know how to use this on a Manipulate source code? When I do CodeFormatterSpelunk[ Manipulate[Plot[Sin[a x], {x, 0, 1}], {{a, 1, "a"}, 1, 10, 1}]] I just get !Mathematica graphics (I am trying to use your program to format my manipulate code, but not able to)....

comment How do I define an argument pattern for a Head of NOT a given value?
can't you just do f[a_Integer] := 2 a; f[a_] := 2000 a ?

comment How to find a specific color in one picture?
@Kuba I think that is a good answer. image = Import["1wEvU.jpg"]; PixelValuePositions[image, Blue, 0.4] gave me {{1605, 810}, {1606, 810}, {1604, 809}, {1605, 809}, ...

comment Solve failing and not clear why
@Amzoti sorry, copied the wrong command. It is Solve, not NSolve. I tried NSolve earlier also to see what it does. But ended up using Solve with Reals.

comment Avoid unnecessary truncation
Just to note, one needs "\" added before [] in the above. But this forum does not show it. So for OP, make sure to add the escape "\" like this: "*****HERE****[ThinSpace]"

comment Avoid unnecessary truncation
You use use the same $PrePrint command, like this: $PrePrint = AccountingForm[#, DigitBlock -> 3, NumberSeparator -> " "] &; I just do not know how to make the separator small.

comment Avoid unnecessary truncation
I think it will be good idea to close this question, since it has an answer already, and post a new question specific to "How to make $PrePrint use AccountingForm with small space for Block separator". This way it will be more specific question, or rename the question, edit as needed.

comment Avoid unnecessary truncation
I think you can using MakeBoxes, but I am not good at that. AccountingForm allready supports setting of DigitsBlocks. Try this: AccountingForm[0.34*60000000, DigitBlock -> 3, NumberSeparator -> ","] But I do not know how to tell it to use small space for separator. Using NumberSeparator -> " " will make the space too large.

comment Avoid unnecessary truncation
You can use 0.34*60000000 // AccountingForm I do not know now to set this to be automatically applied to each number printed. see mathematica.stackexchange.com/questions/20373/… (I think the answer you want is there, just saw it)

comment Why does Mathematica not seem to know that $i^x$ cannot be equal to $0$?
