Solve the DE, together with the given initial conditions, by LT: d 2 y ( t ) dt 2 + 3 dy ( t ) dt + 3 y ( t ) = U ( t ) , t > 0 and y (0) = 0 , ˙ y (0) = 1 (iii) Find f ( t ) given that: F ( s ) = s + 1 s 3 + 6 s 2 + 4 s F ( s ) = s 2 + 4 s s 2 + 2 s + 2 2. Find the Laplace Transform F ( s ) of f ( t ) given that f ( t ) = cos t Z t 0 cos τ dτ + sin t Z t 0 cos τ dτ, t > 0 3.
