f (t)

F(s)

 
Linearity a f (t)+bg(t) aF(s) + bG(s) a,b are constant
Scale change f (at) \frac{1}{a}F\left ( \frac{s}{a} \right ) a>0
Shift e-at f (t) F(s + a)  
Delay f (t-a) e-asF(s)  
Derivation \frac{df(t)}{dt} sF(s) - f (0)  
N-th derivation \frac{d^nf(t)}{dt^n} snf (s) - sn-1f (0) - sn-2f '(0)-...-f (n-1)(0)  
Power t n f (t) (-1)^n\frac{d^nF(s)}{ds^n}  
Integration \int_{0}^{t}f(x)dx \frac{1}{s}F(s)  
Reciprocal \frac{1}{t}f(t) \int_{s}^{\infty }F(x)dx  
Convolution f (t) * g (t) F(s) ⋅ G(s) * is the convolution operator
Periodic function f (t) = f (t+T) \frac{1}{1-e^{-sT}}\int_{0}^{T}e^{-sx}f(x)dx
