# Math Help - primitive of z^2 . e^z^3

1. ## 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

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

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

But this is NOT a definite integral.

5. 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??
