Yes, your favorite impossible integral is back! But all jokes aside, why does this Cases command return empty brackets?
Cases[Integrate[Exp[-2 t^2] t^(9/5) (-t + x)^(4/5) HypergeometricPFQ[{1/2, 1}, {7/5, 19/10}, -3 t^2], {t, 0, x}], _Integrate]
If I put Hold on the Integrate wrapper, it correctly evaluates the pattern. I can't use Hold because I want to see first if Mathematica is able to evaluate the integral first. Since it can't evaluate this integral, the header Integrate should still be present, and pattern evaluate with the expression.
Thanks for any help! Cheers.
