Theorem 12.22 (Inverse Laplace Transform).  Let [Graphics:Images/LaplaceInverseMod_gr_213.gif], where [Graphics:Images/LaplaceInverseMod_gr_214.gif] are polynomials of degree m and n, respectively, and  [Graphics:Images/LaplaceInverseMod_gr_215.gif].  The inverse Laplace transform of  [Graphics:Images/LaplaceInverseMod_gr_216.gif]  is given by  

        [Graphics:Images/LaplaceInverseMod_gr_217.gif][Graphics:Images/LaplaceInverseMod_gr_218.gif],  

where the sum is taken over all the residues of the complex function  [Graphics:Images/LaplaceInverseMod_gr_219.gif].  

Proof.
