Quadrature Newton-Cotes integration

A more accurate and systematic way of evaluating integrals is to perform the integration numerically. In the next two sections, we derive Newton-Cotes integration formulas for equally spaced intervals and Gauss quadrature for unequally spaced points. [Pg.229]

One of the easiest ways to obtain useful quadrature formulas for our purpose is to use Lagrangian interpolation on an equally spaced mesh and integrate the result. This class of quadrature formulas is called the Newton-Cotes... [Pg.1015]

An alternative closed Newton-Cotes quadrature formula of second order can be obtained by a polynomial of degree 1 which passes through the end points. This quadrature formula is called the trapezoid rule. In 2D this surface integral approximation requires the integrand values at the GCV corners. [Pg.1016]

This method has been applied to the behavior of fast reactor clad in the program PECT-1 (48). The problem is solved by taking 11 evenly spaced radii and performing the integrations with the Newton-Cotes quadrature formula. The time-dependent part of the solution is carried out using a... [Pg.86]
