Use Definition 7.1.1.
DEFINITION 7.1.1 Laplace Transform
Let f be a function defined for t 2 0. Then the integral
L{f(t)}
= 60 e-stf(t) dt
/0
L{f(t)} =
is said to be the Laplace transform of f, provided that the integral converges.
Find L{f(t)}. (Write your answer as a function of s.)
f(t) = t cos t
(s > 0)
