SUMMARY
The central difference approximation for the first and second derivatives on a non-uniform grid can be derived similarly to the uniform grid case. The key difference lies in the spacing between grid points, which affects the coefficients used in the approximation. Understanding the specific formulation for non-uniform grids is essential for accurate numerical analysis in differential equations.
