Theorem 12.10  (Laplace Transform).  If  [Graphics:Images/LaplaceTransformMod_gr_68.gif]  is of exponential order, then its Laplace Transform  [Graphics:Images/LaplaceTransformMod_gr_69.gif] exists and is given by

            [Graphics:Images/LaplaceTransformMod_gr_70.gif],   

where  [Graphics:Images/LaplaceTransformMod_gr_71.gif].  The defining integral for  [Graphics:Images/LaplaceTransformMod_gr_72.gif]  exists at points  [Graphics:Images/LaplaceTransformMod_gr_73.gif]  in the right half plane  [Graphics:Images/LaplaceTransformMod_gr_74.gif].

Proof.

Proof of Theorem 12.10.

Proof of Theorem 12.10 is left for the reader in the book.
