Steps in determining the Inverse Laplace Transform of the form e¬as F (s):
In using the formula, E(t) = L-'[e¬as F(s)] = f(t – a)H(t – a), will involved the following steps.
1. Identify the value, a. It is the coefficient of the exponential function.
2. Determine the inverse of the function F(s). The inverse of the function, F(s), will yield f(t).
3. Transform f(t) into f(t-a) by substituting "t-a" in all the "t" variables in the f(t).
4. E(t) is now determined by multiplying the obtained f(t-a) in (3) by H(t-a).
