A Laplace transform converts a function of
t
,
f
(
t
)
, into a new function of
s
,
F
(
s
)
. We denote that as:
L
[
f
(
t
)
]
=
F
(
s
)
where the actual transform can be acquired from a table of Laplace transforms.
For
f
(
t
)
=
t
cos
(
a
t
)
:
L
[
f
(
t
)
]
=
L
[
t
cos
(
a
t
)
]
=
s

a
2
(
s
2
+
a
2
)
2
Therefore, for your function, plug in
a
=
1
to get:
L
[
f
(
t
)
]
=
L
[
t
cos
t
]
=
s
