Step 5 The following Laplace transform from Appendix C can now be used. S Transform 8: f(t) = cos(kt), then 2 {f(t)} = F(s) = 52+ K2 Applying the above with k = 8 and solving for /{y} gives the following result. (s2 + 64)2(y} = _{cos(8t)} - e-* {cos(8t)} + 1 S S (s2 + 64 ) Z(y) = - e 2 + 1 2 + 8 2 S 2 se S 1 2 + (52 + 64)2 $2 + 64 Submit Skip (you cannot come back)
