Second Order Exact Differential equations
The second order linear differential equation
P ( x) y +Q ( x) y+R ( x) y =0
is called exact if it can be written in the form
( P( x) y)+( S ( x) y )
Inverse Laplace Transform:
If L[f(x)] = F(p), then f(x) is called an inverse
Laplace transform of F(p), and we write
f(x) = L-1[F(p)].
