It seems to be correct. Yes indeed, if you do a series expansion about zero for both forms of the integral the coefficients are identical (at least as far as I went) except for the constant term, which is obviously arbitrary. I wonder, does this mean that Mathematica does not 'know' how to translate this particular hypergeometric, or is it that it does not 'simplify' hypergeometrics if the result in terms of elementary functions is excessively complicated.
