comment `Series` acts on variables outside its argument?
I really don't understand your question. Are you just trying to compute $f(h)_\text{exact} - f(h)_\text{taylor}$? In that case you should be using f[h] - Series[f[h + δ], {δ, 0, 2}]

comment Proving that Reverse[Reverse[x]]]=x
I think this is the reason the developers introduced Inactive in version 10: so that symbols like Reverse can be deactivated for symbolic manipulation. Do you agree with my comment to OP?

comment Proving that Reverse[Reverse[x]]]=x
Reverse is an active function. There is no built-in symbolic representation of Reverse upon which analysis can be carried out. I have found that you can use Mathematica's analysis capabilities on symbols which in the documentation are noted as being "suitable for symbolic manipulation."

comment Why does WordList[“KnownWords”] include so many non-words?
{"wow", "Noun"} -> "a joke that seems extremely funny" Next time someone asks me to tell a joke, I'll just say 'wow'.

comment Branch cuts of sqrt
@ChipHurst Are the branch cuts drawn by Mathematica really determined by ComplexAnalysis`BranchCuts? Or is ComplexAnalysis`BranchCuts just a novelty function not used anywhere?

comment Getting Arg[z] to go from $0$ to $2\pi$
Did you copy the timings correctly? On my machine Mac OS X 10.11, ArcTan is definitely slower than Arg in Mathematica 10.4, 10.3, 9.0 and 8.0.4. On 10.3 they timings are {0.016644, 0.025684, 0.090886} on my machine.
