Finite Difference Method: In this method, differential equations are solved by approximating derivatives with finite differences. It is commonly used to solve partial differential equations.
Finite Element Method: This method is used to solve a wide range of problems from structural engineering to fluid mechanics. It involves dividing the physical domain into smaller, finite elements which are then analyzed using numerical methods.
Monte Carlo Method: This method uses random sampling to solve problems that would otherwise be difficult or impossible to solve analytically. It is used in physics, finance, and many other fields.
Spectral Method: This method is a numerical technique for solving differential equations in which the solution is represented as a sum of basis functions that are carefully chosen to satisfy boundary conditions.
Boundary Element Method: This method is used to solve boundary value problems by dividing the boundary into elements and using numerical methods to solve the equations.
Finite Volume Method: In this method, the physical domain is divided into smaller volumes, and the equations governing the system are integrated over these volumes.
Runge-Kutta Method: This numerical method is commonly used to solve ordinary differential equations. It involves a set of formulas to approximate the solution iteratively over small time steps.
Gauss-Seidel Method: This iterative method is used to solve linear systems of equations by computing the unknowns one at a time in a systematic manner.
Newton-Raphson Method: This method is used to find the roots of a function by using a series of approximations based on the previous iteration.
Fast Fourier Transform: This is a numerical algorithm used to efficiently compute the discrete Fourier transform of a sequence. It is widely used in signal processing, audio and image compression, and other fields.
