Integrate
$$int x^2 e^x^3cosx^3 dx$$
I have tried it by every possible method using By Parts as Taking x^3 as t then integrating but it didn't work.

$$int x^2 e^x^3cos(x^3) dx$$

Substitute $u=x^3$ and $du=3x^2dx$ gives us

$$frac13int e^ucos(u) du$$

This one should be clear. If not try integration by parts or search for it in a integral table.
