primitive of z^2 . e^z^3
I've hit a wall here, stuck on the primitive of z^2 . e^z^3......any light taht can be shed would me much appreciated(Worried)

Do you mean $\int{x^{2}e^{x^3}}dx$?
Use the u-substitution and let $u=x^3$

Thanks for prompt reply.........I probably should have said I'm using the Fundamental Therom of Calculus?? Does the latter still hold?(Wondering)

But this is NOT a definite integral.

Not 100% confident on this...hence the S.O.S....... I believe they're contour integrals I'm working on? F is a primitive of f on R (if F is analytic on R) and F'(z) = f(z).......if that's any clearer??
