So the true value of the integral is between 0.74512 − 0.0047 = 0.74042 and 0.74512 + 0.0047 = 0.74982. Unfortunately, the first rounds to 0.74 and the second rounds to 0.75, so we can't be sure of the correct value in the second decimal place; we need to pick a larger n .

In numerical analysis, a quadrature rule is an approximation of the definite integral of a function, usually stated as a weighted sum of function values at specified points within the domain of integration. Numerical Integration An integral can be seen as the area under a curve. Given ) = !(#)the approximation of the Area (5) under the curve can be found dividing the area up into rectangles and then summing the contribution from all the rectangles (trapezoid rule): Chapter 5: Numerical Integration and Differentiation PART I: Numerical Integration Newton-Cotes Integration Formulas The idea of Newton-Cotes formulas is to replace a complicated function or tabu-lated data with an approximating function that is easy to integrate.

Numerical (data-based) integration is fundamentally a two-step arithmetic process. First, we must use multiplication to calculate the product of a variable and a small increment of another variable (a change in the second variable between two different points). Then, we must use addition to calculate the accumulated sum of the products.

Integration (or Richardson’s extrapolation). Romberg Integration n2 C E t! where C is an approximately constant If I true = true value and I n= approx. value of the integral I true ≈ I n + E t E t(n) ≈ C/n2≈ I true - I n E t(2n) ≈ C/4n2≈ I true - I 2n Therefore, eliminate C/n2 between these two equations!
