Mathematica evaluates correctly the following integral:
ff = HoldForm[Integrate[Sin[x^3]*Log[x], {x, 0, 1}]]
ff//ReleaseHold
{N@%,ff/.Integrate[x___]\[RuleDelayed]NIntegrate[x]//ReleaseHold}
(-(1/16))*HypergeometricPFQ[{2/3, 2/3}, {3/2, 5/3, 5/3}, -(1/4)]
{-0.060865478966467726, -0.06086547896286495}
However...
Integrate[Sin[x^3]*Log[x + 5], {x, 0, 1}]
Integrate[Sin[x^3]*Log[x + 5], {x, 0, 1}]
Any ideas about evaluating symbolically previous integral?
Thanks in advance!
