### solve differential equation using Laplace transform

1. Solve y''+4y'+4y=g(t) using Laplace transforms.... y(0) = 2; y'(0)=-3 Express the answer in terms of a convolution integral 2. Find the inverse of F(s) = 1/[(s^4)(s^2+1)] the answer can be left as a convolution integral 3. Solve y''''+5y''+4y=g(t) using laplace transforms.... y(0) = 1; y'(0)=y''(0)=y'''(0)=0 E
