\[X(s)={1 \over s}- {e ^{-2s} \over s}\]

AnwarA, can you explain how you found that? did you just use a laplace transform table?

you can use the definition of laplace transform

lemme see if i can make it readable

\[\int\limits_{0}^{\infty}e^(-s*t)f(t)dt\]
anonymous
  • anonymous
well you can easily do it using the Laplace definition or this formula for laplace transform of the unit step function: \[L[u(t-a)]={e ^{-as} \over s}\]

  • anonymous
yea, that didn't work, well, you can ignore when the step function is zero, and integrate where t > 0, or t-2 > 0
