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 # %?` );
