4.1.6. Properties of the unilateral Laplace transform

These are from the Wikipedia page on the Laplace transform

Laplace Transform Properties
  Time Domain \(s\)-Domain Remark
Linearity \(a\,x(t)+b\,y(t)\) \(a\,X(s)+b\,Y(s)\)  
Differentiation \(x'(t)\) \(sX(s)\) \(x(0)=0\)
Integration \(\int_0^t f(u)du\) \(\frac{1}{s}X(s)\)  
Convolution \(x(t)\ast y(t)\) \(X(s) Y(s)\)
