SUMMARY
The discussion focuses on the integration of the function $$\int x^2\cos(mx)\,dx$$ using integration by parts. In this context, $x^2$ is designated as $u$ and $\cos(mx)\,dx$ as $dv$. It is clarified that when integrating with respect to $x$, the variable $m$ is treated as a constant unless it is explicitly defined as a function of $x$. This distinction is crucial for correctly applying integration techniques.
