To get the Laplace Transform (easily), we decompose the function above into exponential form and then use the fundamental transform for an exponential given as : L{u(t)e−αt} = 1 s + α L { u ( t) e − α t } = 1 s + α. This is the unilateral Laplace Transform (defined for t = 0 t = 0 to ∞ ∞ ), and this relationship goes a long way ...}}

To solve differential equations with the Laplace transform, we must be able to obtain $f$ from its transform $F$. There’s a formula for doing this, but we can’t use it because it requires the theory of functions of a complex variable. Fortunately, we can use the table of Laplace transforms to find inverse transforms that we’ll need.
