We dont use fourier transforms because we are dealing with the transient response and because a fourier transform wont handle a system that blows up. Besides being a di erent and e cient alternative to variation of parameters and undetermined coe cients, the laplace method is particularly advantageous for input terms that are piecewisede ned, periodic or impulsive.

Laplace transforms we use laplace transforms because we are dealing with linear dynamic systems and it is easier than solving differential equations.

The denominator is already nicely factored, so we can use partial fractions to break this up into several fractions that we can take the inverse laplace transform of using tables. However in some cases it may be necessary to use the inverse integral defined below.

In many cases of interest, the inverse laplace transform can be found from partial fraction expansions.
