[tex]\int xe^{2x^2} cos(3x^2) dx[/tex]

This is the hardest integral I've attempted so far. I've come up with an answer that fits a table in my book but I'm not sure if I arrived there correctly. Thanks for reading!

2. Relevant equations

[tex]\int e^{au} cos\ bu\ du\ = \frac{e^{au}}{a^2+b^2}(a\ cos\ bu\ + b\ sin\ bu)+C[/tex]

3. The attempt at a solution
