Step 3: Invert the Laplace transform ( invlaplace )
An explicit formula for the solution of the ODE or IVP is found by inverting the Laplace transform with the invlaplace command:
> soln := invlaplace( solnLT, s, t );
>
Assuming the solution contains no parameters, the solution can be plotted as follows:
> plot( rhs(soln), t = %? .. %?,
> title = `Solution for Problem # %?` );
