Help needed : I can't - and Mathematica 5.0 can't either - integrate this : In[1]:= Integrate[x^2 / E^(a*(1 - 2*x^2)^2), {x, 0, 1}, Assumptions -> a >= 0] Out[1]= (2*Integrate`TableDump`c$70*E^Integrate`TableDump`c$70^2 - Sqrt[Pi]*Erfi[Integrate`TableDump`c$70])/E^(5*a)/ (4*Integrate`TableDump`c$70^3) Thanks in advance for any hint. v.a.
