Use the Laplace transform to solve the following initial value problem:
y" + 6y' = 0
y(0) = 6, y'(0) = ?
First, using Y for the Laplace transform of y(t), i.e., Y = L{y(t)}; find the equation you get by taking the Laplace transform of the differential equation.
Now solve for Y(s) and write the above answer in its partial fraction decomposition: Y(s) = Y(s)
where a < b.
Now, by inverting the transform, find y(t).
