Integral Too Hard For Mathematica
This problem can be solved numerically by
s = ParametricNDSolveValue[{z'[t] == Exp[-2 t^2] t^(9/5) (x - t)^(4/5)
HypergeometricPFQ[{1/2, 1}, {7/5, 19/10}, -t^2], z[0] == 0}, z, {t, 0, x}, {x}];
Plot[s[x][x], {x, 0, 5}]
As noted by Marius Ladegård Meyer in a comment above, NDSolve
itself is not sufficient, because x
appears both in the integrand and as the upper limit of integration.
