Things You Should Know

Laplace Transform

F(s)=\int_{0}^{\infty}f(t)e^{-st}dt

s = \sigma+i\omega

Derivative Transforms

f^{'}(t)\Rightarrow{s}F(s)-f(0^{-})

f^{''}(t)\Rightarrow{s^{2}}F(s)-sf(0^{-})-f^{'}(0^{-})

Integral Transform

\int_{0}^{t}f(\tau)d\tau\Rightarrow\dfrac{1}{s}F(s)

Electrical Components

Resistor

v=iR\Rightarrow{V(s)}=RI(s)

Inductor

v=L\dfrac{di}{dt}\Rightarrow{V(s)}=L[sI(s)-i(0^{-})]

Capacitor

i=C\dfrac{dv}{dt}\Rightarrow{I(s)}=C[sV(s)-v(0^{-})]
