How do I approach integration by parts when both functions seem equally complex?
I'm struggling with integrals like ∫x·e^x·sin(x)dx. The LIATE rule suggests choosing u = x, but then I still have two functions left. Has anyone found a systematic approach for these triple-function integrals? Any tips or resources would be really appreciated!
