comment I cannot pass any script to `math`, in a command line
if you just run math do you get the kernel input prompt, can you run these examples interactively?

comment Polar histogram
+1 nice, but you "shamelessly" copied my mistake :).. Also BTW SectorOrigin->0 will make this look more like a standard polar plot.

noting you say cant pass "any script", try simply Print["hello world"]

comment I cannot pass any script to `math`, in a command line
Ive just checked, Put works fine using -script or -initfile (i.e. this is not related to the Export issue ). Have you tried w/o the full path?

comment Numerical integration with symbolic coefficients
maybe @MichaelE2 should elaborate on his other answer, but it works because that example can be broken into a sum of integrals with the symbolic constants pulled out of each. "no chance" that will work with this complicated expression.

comment Inconsistent results for Integrate depending on irrelevant assumptions
looks like perhaps changing the assumptions is impacting the default generateconditions behavior. see what you get if you explicitly set that.

comment Is it possible to have Logarithm with base 1 or 0?
if that math.se link doesnt answer your question you should post a new question on math.se, making it clear how your question is different.

comment Exporting to eps loses font/symbol information?
interesting, on inspection on both my systems (windows and linux ) the mathematica fonts are embedded in the eps. Can you open an example in a text editor and look for /FontName /Mathematica1 def ? If its there maybe your problem is with your viewer..

@belisarius. Still an interesting thing to show, you ought to update the answer

comment Exporting to eps loses font/symbol information?
The issue is it wants to render the parenthesis using mathematica fonts. I don't see a work around. Can you see if you have the same issue with "pdf" (That should properly embed the font..).

comment Exact difference between color scaling in ArrayPlot and MatrixPlot
Its really not clear exactly what he's after, I took it to be more about the look of the figure..

comment converting miles into inches from wolframalpha
Using precision implied by significant figures the "correct" answer is 16000. And how come .250005 -> 15840` not 15840.3 ?

comment How to replace all symbols except several?
In this example this works .. eq /. Cases[ Variables[eq] , v : Except[a | d] :> v -> 1 ]

comment Integration with mathematica?
This is an example where it is far easier to do the substitution by hand and feed theIntegral in terms of u to mathematica.

comment How to obtain all solutions for Cos[x] Cosh[x] == 1?
NSolve is about 10x faster than Solve // N . FindRoot is in turn 10x faster in this case since we can trivially feed it very close guesses..

comment Infinite sums with Boole and EvenQ
You probably know this but in this case you can readily handle it manually: Sum[x/x!, {x, 2, Infinity, 2}]. Search this site and you'll find a few examples of more complicated cases that cant readily be treated like that and unfortunately there is no general solution.
