Now that we have figured out how to do step 1, we are going to try and do steps 1 and 2. Given the
differential equation
y" + 3y' + 5y = 0, y(0) = - 2, y'(0) = 1
Apply the Laplace Transform and solve for Y(s) = L{y}
Y(s) =
To solve an initial value problem using the Laplace transform takes three steps.
1. Take the Laplace transform of both sides of your ODE. This transforms your ODE into an ALGEBRAIC
equation!
2. Solve the resulting algebraic equation for Y(s)
3. Take the inverse Laplace transform. Your result is the solution, y(t).
