Homework Statement
Find the Laplace Transform from the definition of f(t) = tcos(2t)
Homework Equations
[tex]\int e^-^s^ttcos(2t)dt[/tex]
The Attempt at a Solution
I started by doing parts
[tex]u = t[/tex]
[tex]du = dt[/tex]
[tex]dv = cos(2t)e^-^s^t dt[/tex]
but I get stuck on v and as far as I can tell doing parts on v won't help because neither term will be reduced when differentiated.
I'm looking for some direction on how to solve this integral.
Thanks!
