Example 1. Approximate the integral of f( x ) = x 3 on the interval [1, 2] with four subintervals. First, h = (2 - 1)/4 = 0.25, and thus we calculate:

For example, Figure 1 shows a single application of the trapezoidal rule. Figure 1. The integral of cos(x) on [0, π/2] approximated with one trapezoid. Figure 2 shows the trapezoidal rule applied to four sub-intervals on the interval [0, π/2].
Instead for higher accuracy and its control, we can use the composite (also called multiple-segment) trapezoidal rule where the integral is broken into segments, and the single-segment trapezoidal rule is applied over each segment.

31 maj 2022 · Trapezoidal rule. We suppose that the function \ (f (x)\) is known at the \ (n+1\) points labeled as \ (x_ {0}, x_ {1}, \ldots, x_ {n}\), with the endpoints given by \ (x_ {0}=a\) and \ (x_ {n}=b\). Define.
9 lut 2018 · The composite trapezoidal rule is a method for approximating a definite integral by evaluating the integrand at n points. Let [ a , b ] be the interval of integration with a partition a = x 0 < x 1 < … < x n = b .
Quadrature error estimate for composite Simpon’s rule. Let f ∈ C 4 ( a,b ), then the quadrature error I [ f ] −CT[ f ] for the composite trapezoidal rule can be estimatedby
