Laplace transform - Wikipedia
https://en.wikipedia.org/wiki/Laplace_transform
WebThe Laplace transform's key property is that it is converts differentiation and integration in the time domain into multiplication and division s in the Laplace domain. Thus, the Laplace variable s is also known as operator variable in the Laplace domain: either the derivative operator or (for s −1 ) the integration operator .
