Formula for the use of Laplace Transforms to Solve Second Order Differential Equations. Given the differential equation ' y (0) y' ) 0 ( ), ( ' ' ' 0 , 0 y y t g cy by ay we have c bs as t g L ay y b as y L 2 0 0 )) ( ( ' ) ( ) ( We get the solution y(t) by taking the inverse Laplace transform. The following table are useful for applying this technique.
