In quasi-steady-state creeping flow it is possible to combine the mass conservation equation and the momentum equation to generate a new equation in terms of the stream function Y: (V*y = 0). Here, V* is called the biharmonic operator. In cartesian coordinate, this operator is defined at az +2- ax Derive a second order central difference discretization of the biharmonic equation.
