Jun6 comment Numerical Integration in Laplace domain eq3and eq4 have "n" it it, so you should use eq3[s_?NumericQ,n_?NumericQ] for these and call them in PD with 2 parameters. And you should use PD[s_]:=.... Than you can call e.g. PD[2] and get a value (0.0182218 + 0.0011354 I`). But the integrals seem to convert badly, because you'll get a bunch of messages, so you can't trust this value.
