25 lip 2021 · The most commonly used techniques for numerical integration are the midpoint rule, trapezoidal rule, and Simpson’s rule. The midpoint rule approximates the definite integral using rectangular regions whereas the trapezoidal rule approximates the definite integral using trapezoidal approximations.

21 gru 2020 · Approximate the following integrals using either the midpoint rule, trapezoidal rule, or Simpson’s rule as indicated. (Round answers to three decimal places.) Exercise \(\PageIndex{1}\)
The Midpoint Rule is a numerical method used to approximate the value of a definite integral. It provides a way to estimate the area under a curve, which is particularly useful when the integral cannot be calculated directly.
The integral \(\displaystyle\int_{-1}^{1} \sin(x^2) \, \dee{x}\) is estimated using the Midpoint Rule with \(1000\) intervals. Show that the absolute error in this approximation is at most \(2\cdot 10^{-6}\text{.}\)
Midpoint & trapezoidal sums. Approximate the area between the x -axis and f ( x) = ( x − 3) 2 from x = 0 to x = 6 using a midpoint Riemann sum with 3 equal subdivisions.

1.11.1 The midpoint rule. The integral ∫xjxj − 1f(x)dx represents the area between the curve y = f(x) and the x -axis with x running from xj − 1 to xj. The width of this region is xj − xj − 1 = Δx. The height varies over the different values that f(x) takes as x runs from xj − 1 to xj.
