\(

\int e^{-t} * sin(2 \pi f_c t) * e^{-j2 \pi ft} dt

\)

I have tried two methods: 1) integration by parts, and 2) integration after expressing the sine function as a complex exponentials. I get stuck in both cases.

The asterisks are there to assist with clarity of spacing. Thanks for any help you can provide,
