Re: Another question on Integrate

My guess is that this integral (and the like) can only be given explicitly
in terms of power series (cf. Tables of Integrals and Other Mathematical
Data, by H.B. Dwight, 481.2). See, e.g.,

Integrate[Series[Tan[x]/x, {x, 0, 10}], x]
SeriesData[x, 0, {1, 0, 1/9, 0, 2/75, 0, 17/2205, 0,
   62/25515, 0, 1382/1715175}, 1, 12, 1]

(Convert the output cell to standard form).
