comment Import EPS and use as symbol
If the simple Import is failing that's really separate question. Do a search if folks have had issues with Illustrator/Eps and maybe post an example file.

+1 I can confirm this works with eps generated from outside mathematica as well.

comment Export Text with Colors
For starters you need so specify a file type that supports colors. pdf , html ? depends of what you are trying to do.

comment Want NIntegrate to catch error message
To the second part, see $MessagePrePrint for extracting the numbers.. they are often garbage though so I'm not sure thats a worthwhile thing to do.

comment Want NIntegrate to catch error message
Try this : Quiet[Check[ NIntegrate[Sin[x], {x, 0, 10000}, Method -> { Automatic, "SymbolicProcessing" -> False}] , "invalid"] ] . Its pretty much what you say you tried though..

comment How can I import a table from a Wikipedia page?
You can alwars just use Import : Import["http://en.wikipedia.org/wiki/List_of_missions_to_the_Moon", {"HTML", "Source"}] . ( WikipediaData doesn't work for me either by the way )

you can readily get the result analytically, a b (a+b)^2 times 4 if both odd.

comment slope of tangent at each point
looks like experimental data that would be well fit by a line. What are you actually trying to acomplish?

even simpler, FindInstance[ x^2 + y^2 == z^2 + 1 && 1 < x && 1 < y && 1 < z, {x, y, z}, Integers] but note this and @2012rcampion form can only apparently find the one {4,7,8} solution.

comment Random variates drawn from a multivarite t distribution
Goto is bad enough, in this case if we ever got-to the go-to it would loop endlessly.

comment Switch from logarithmic to linear scaling partway along a plot's axis
similarly you can do ParametricPlot[{inverseg[x], Sin[x]}, {x, 1, 100}, .. (perhaps preferable for readability sake )
