# Finite difference method homework

Short essay description
Measurable Outcome 2. Finite difference methods for PDEs are essentially built on the same idea, but approximating spatial derivatives instead of time derivatives. Finite difference approximations can also be one-sided. For example, a backward difference approximation is,. We can also derive finite difference approximations for higher-order derivatives.  ## Simple Codes for Learning CFD    ## Math Numerical Methods II

Instructor: Prof. Phone: Office hours: Mon. Course Description back to top. This course is on the finite element methods FEM for solving elliptic and time-dependent partial differential equations PDEs. It covers the mathematical formulation, numerical analysis, and efficient computations of FEM, with applications to continuum mechanics. It also surveys some advanced, research-oriented topics, including shock capturing, high-order and super-convergence, mesh adaptation, multigrid methods, domain decomposition, and hybrid methods.

In numerical analysis , finite-difference methods FDM are a class of numerical techniques for solving differential equations by approximating derivatives with finite differences. Both the spatial domain and time interval if applicable are discretized , or broken into a finite number of steps, and the value of the solution at these discrete points is approximated by solving algebraic equations containing finite differences and values from nearby points. Finite difference methods convert ordinary differential equations ODE or partial differential equations PDE , which may be nonlinear , into a system of linear equations that can be solved by matrix algebra techniques. Modern computers can perform these linear algebra computations efficiently which, along with their relative ease of implementation, has led to the widespread use of FDM in modern numerical analysis. First, assuming the function whose derivatives are to be approximated is properly-behaved, by Taylor's theorem , we can create a Taylor series expansion.
