(Solved): Use the following theorem. If F(s)=L{f(t)} and n=1,2,3,dots, then L{t^(n)f(t)}=(-1)^(n)(d^(n))/(ds^( ...
Use the following theorem. If
F(s)=L{f(t)}and
n=1,2,3,dots, then
L{t^(n)f(t)}=(-1)^(n)(d^(n))/(ds^(n))F(s). Evaluate the given Laplace transform. (Write your answer as a function of
s.)
L{6t^(2)cos(t)}
