What are numerical integration methods?
Numerical integration methods can generally be described as combining evaluations of the integral to get an approximation to the integral. The integral is evaluated at a finite set of points called integration points and a weighted sum of these values is used to approximate the integral.
Which numerical integration method is best?
It depends on the problem, for example if the integrand is a smooth function the gaussian quadrature methods is the best, but if integrand is not smooth it is better we use local methods such as simpson. but it depends that how much the integrand is smooth.
Which rule is a method for numerical integration?
Simpson's rule is one of the numerical methods which is used to evaluate the definite integral. Usually, to find the definite integral, we use the fundamental theorem of calculus, where we have to apply the antiderivative techniques of integration.
How do you solve numerical differentiation and integration?
We can find differentiation formulas using specific points. E.g. U se /(x) , /(x + h) and /(x - h) to find an expression for /''(x). We begin by writing the Taylor series for /(x) , /(x + h) and /(x - h). Solve A/(x + h) + B /(x) + C /(x - h) = /''(x) + with the best error we can get.
