How can I solve wave equation for circular membrane in polar coordinates?
- With Neumann or Neumann-like (e.g. Robin) conditions you want to be careful that you discretize the boundary derivative in a way which has the same order as your discretization of the interior derivatives

Graph Theory
It explores graph theory concepts, including definitions, basic graph analysis, graph partitioning methods like the Fiedler Method, and practical applications using Matlab for graph representation and matrix calculations.

Numerical differentiation: finite differences
Finite difference formulas are used to approximate derivatives of a function at a point by utilizing data points. Different orders of approximations are derived for various situations in numerical differentiation.

- In New York, people speak fast. In the American South, they speak slowly. Both of them are a form of politeness, understood in a different way. In New York, you speak quickly because you respect the value of the other person’s time and you don’t want to take up too much of it. In the South, you speak slowly because you want to respect the person by... See more
