Study Notes

  • The Laplace Transform of a function $f(t)$ defined for $t \ge 0$ is given by the integral $F(s) = \int_{0}^{\infty} e^{-st} f(t) dt$, provided the integral converges.
  • $F(s)$ is the notation for the Laplace Transform of $f(t)$, written as $F(s) = L{f(t)}$.
  • The Laplace Transform changes a function of $t$ into a function of $s$.
  • Only values of $t \ge 0$ are considered.

Example Laplace Transforms

  • $L{1} = \frac{1}{s}$ for $s > 0$.
  • $L{e^{at}} = \frac{1}{s-a}$ for $s > a$.
  • $L{sin(at)} = \frac{a}{s^{2} + a^{2}}$ for $s > 0$.

Laplace Transforms Table

  • For $f(t) = 1$, $F(s) = \frac{1}{s}$ where $s > 0$.
  • For $f(t) = e^{at}$, $F(s) = \frac{1}{s-a}$ where $s > a$.
  • For $f(t) = sin(at)$, $F(s) = \frac{a}{s^{2} + a^{2}}$ where $s > 0$.
