Sympy provides a function called laplace_transform which does this more efficiently. By default it will return conditions of convergence as well (recall this is an improper integral, with an infinite bound, so it will not always converge). If we want just the function, we can specify noconds=True. 20.3.

On occasion we will run across transforms of the form, \[H\left( s \right) = F\left( s \right)G\left( s \right)\] that can’t be dealt with easily using partial fractions. We would like a way to take the inverse transform of such a transform. We can use a convolution integral to do this. Convolution Integral
