How do I use the Bromwich inversion formula to find inverse Laplace transforms?
$$ f(t)= \frac{1}{2\pi i} \int \limits_{c-i\infty}^{c+i\infty} e^{st} F(s)ds $$
I read in a complex analysis book to take only the residues, but how does that work? The "contour" is just a single line. And how do I choose the constant c?
