How can I integrate 2x^2*exp(x^3)?

    How can I integrate 2x^2*exp(x^3)?

    exp(x^3) has no elementary antiderivative, does it?

    Yes, you can integrate [tex]\int 2x^{2} e^{x^{3}} dx[/tex] by parts.

    No, we don't integrate that expression by part. o:)
    A simple u-substitution should work, let u = x3, and see if you can continue from there. :)

    My apologies. :) I didn't look at the x^2 term that well.

    Try d/dx (e^[x^3])

    Could you imagine doing that by parts!?

    It would take two steps, and be all long. Oh boy.
