Laplace Transform

Definition of Laplace Transform

Let   f(t)   be a given function which is defined for   t0. If there exists a function   F(s)  so that
 

F(s)=0estf(t)dt,

 

then   F(s)   is called the Laplace Transform of   f(t), and will be denoted by   L{f(t)}.   Notice the integrator   estdt   where   s   is a parameter which may be real or complex.
