## What is Numerical Method?

Numerical method is a branch of mathematics that deals with finding approximate solutions to complex problems using numerical calculations. Numerical methods are often used when exact solutions are impossible or impractical to obtain using analytical methods. For example, numerical methods can be used to solve differential equations, integrate functions, optimize systems, simulate physical phenomena, and so on.

### Definition and examples of numerical methods

A numerical method can be defined as a sequence of steps or algorithms that transform a given problem into a simpler one that can be solved using arithmetic operations. The accuracy and efficiency of a numerical method depend on various factors, such as the choice of algorithm, the number of iterations, the error tolerance, the stability, and the convergence. Some common examples of numerical methods are:

Root-finding methods: These are methods that find the values of x that satisfy f(x) = 0, where f is a given function. For example, the bisection method, the Newton-Raphson method, the secant method, etc.

Interpolation methods: These are methods that estimate the value of a function at a given point using known values of the function at other points. For example, the Lagrange interpolation, the spline interpolation, the polynomial interpolation, etc.

Numerical integration methods: These are methods that approximate the value of an integral using a finite sum of terms. For example, the trapezoidal rule, the Simpson's rule, the Gaussian quadrature, etc.

Numerical differentiation methods: These are methods that approximate the value of a derivative using finite differences. For example, the forward difference, the backward difference, the central difference, etc.

Numerical linear algebra methods: These are methods that solve systems of linear equations or find eigenvalues and eigenvectors of matrices using numerical techniques. For example, the Gaussian elimination, the LU decomposition, the Jacobi method, the power method, etc.

Numerical optimization methods: These are methods that find the minimum or maximum value of a function subject to some constraints using numerical algorithms. For example, the gradient descent method, the Newton's method, the simplex method, etc.

Numerical ordinary differential equation methods: These are methods that solve initial value problems or boundary value problems involving ordinary differential equations using numerical schemes. For example, the Euler method, the Runge-Kutta method, the finite difference method, etc.

Numerical partial differential equation methods: These are methods that solve partial differential equations using numerical discretization and approximation techniques. For example, the finite element method, the finite volume method, the finite difference method, etc.

### Applications and benefits of numerical methods

Numerical methods have a wide range of applications in various fields of science, engineering, and technology. Some examples are:

Computational fluid dynamics: This is the study of fluid flow using numerical simulations and models. Numerical methods can be used to solve the Navier-Stokes equations, which describe the motion of fluids, and to analyze the effects of turbulence, viscosity, pressure, temperature, etc.

Computational physics: This is the study of physical phenomena using numerical models and simulations. Numerical methods can be used to solve the Schrödinger equation, which describes the behavior of quantum systems, and to model the interactions of particles, waves, fields, etc.

Computational chemistry: This is the study of chemical reactions and structures using numerical calculations and simulations. Numerical methods can be used to solve the molecular Hamiltonian, which describes the energy and dynamics of molecules, and to perform molecular dynamics, quantum chemistry, etc.

Computational biology: This is the study of biological systems and processes using numerical models and simulations. Numerical methods can be used to solve the reaction-diffusion equations, which describe the transport and transformation of substances in biological systems, and to model the behavior of cells, tissues, organs, etc.

Computational finance: This is the study of financial markets and instruments using numerical models and simulations. Numerical methods can be used to solve the Black-Scholes equation, which describes the price of options and derivatives, and to perform risk analysis, portfolio optimization, etc.

Numerical methods have many benefits over analytical methods in solving complex problems. Some of them are:

Numerical methods can handle problems that are nonlinear, high-dimensional, or have no closed-form solutions.

Numerical methods can provide approximate solutions with a desired level of accuracy and precision.

Numerical methods can be implemented using computers and software tools that can perform large-scale computations efficiently and reliably.

Numerical methods can be adapted and modified to suit different situations and requirements.
