    Band 1,S. These are known as Gauss-Jacobi quadrature rules, i. This exact rule is known as the Gauss-Legendre quadrature rule. Categories : Numerical analysis Numerical integration quadrature. Categories : Numerical integration quadrature. By differentiating both sides of the above with respect to the argument xit is seen that the function F satisfies. The quadratures of a sphere surface and a parabola segment done by Archimedes became the highest achievement of the antique analysis. Main article: Monte Carlo integration. For the integral of a Gaussian function, see Gaussian integral. Numerical integration methods can generally be described as combining evaluations of the integrand to get an approximation to the integral.

    Lobatto Quadrature from Wolfram MathWorld

    To compute integrals in multiple dimensions, one approach is to phrase the multiple integral as repeated one-dimensional integrals by applying Fubini's theorem the tensor product rule. Problems of quadrature for curvilinear figures are much more difficult. Numerical integration methods can generally be described as combining evaluations of the integrand to get an approximation to the integral.

    Generalized Laguerre polynomials. Then again, if h is already tiny, it may not be worthwhile to make it even smaller even if the quadrature error is apparently large.

    This can be answered by extrapolating the result from two or more nonzero step sizes, using series acceleration methods such as Richardson extrapolation. In response, the term quadrature has become traditional, and instead the modern phrase " computation of a univariate definite integral " is more common.
