Example (cont.): 2 Alternatively, using PFD, we write: F(s) = 1 (s 2)(s + 1) = A s 2 + B s + 1 = A(s + 1) + B(s 2) (s 2)(s + 1); then A(s + 1) + B(s 2) = 1, and setting s = 1 : B( 3) = 1 B = 1=3 s = 2 : A 3 = 1 A = 1=3 … Webb1 Piecewise Functions In the motivation for Laplace Transforms, we were led to believe that one of the primary advantages of this method is that it easily handles non-smooth …
Webb1 Piecewise Functions In the motivation for Laplace Transforms, we were led to believe that one of the primary advantages of this method is that it easily handles non-smooth and even discontinuous forcing functions (i.e. nonhomogeneities). In order to handle such cases, we must expend a little energy developing the framework for the Laplace ... WebbExpert Answer.
