Question
a. Set up an integral for finding the Laplace transform of the following function:
0,
0 <t< 8
f(t)
t – 3,
8 < t.
B
F(s) = L {f(t)} = /
help (formulas)
(e^(-st))(t-3)dt
where A = 8
and B =
inf
b. Find the antiderivative (with constant term 0) corresponding to the previous part.
-(-5e^(-8s)/s-e^(-8s)/s^(2))
c. Evaluate appropriate limits to compute the Laplace transform of f(t):
F(s) = L {f(t)}
e^(-8s)(s+1)/s^2
d. Where does the Laplace transform you found exist? In other words, what is the domain of F(s)?
(0,inf)
