![Find the Laplace transform F(s) = L[f(t)] for each of the following functions. For full credit,
show all of your work by expanding each Laplace transform into one or more Laplace transforms
of the common functions listed in the provided Laplace Transform Table. Indicate which rows of
the table you used to obtain your solution and fully simplify the result to a single term.
1. f(t) eat+b where a, b are constant
=
2. f(t) = sin(wt - p) where w, p are constant
3. f(t) = ³-1/2
4. f(t) = (e-¹/4) [2+t² + cos(3t)]. (Note: For this problem there is no need to simplify to a
common denominator.)
