Foil 11 Central Difference Operator with error O(h2)

From CPS615 Module on Iterative PDE Solvers CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox

Solve previous equation for 2nd derivative

Combine with similar equation in y direction

Backward difference operator and forward difference operator are O(h)

Higher order operators use more points on the grid (larger stencil) and are more accurate
