Hi, I have the following integral which I am not confident on how to interpret (solve):\begin{equation}
\alpha \bigg( \int_0^L [\frac{d^3}{dx^3}\phi] \psi dx - \int_0^L [\frac{d^3}{dx^3}\psi] \phi dx \bigg)
\end{equation}
at this stage, I am not sure which rule to use to solve each of the two integrals in the brackets, or simplify them.
Is this possible to be simplified?
Thanks!
