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.
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 midpoint rule for estimating a definite integral uses a Riemann sum with subintervals of equal width and the midpoints, mi m i, of each subinterval in place of x∗ i x i ∗. Formally, we state a theorem regarding the convergence of the midpoint rule as follows. The Midpoint Rule. Assume that f (x) f ( x) is continuous on [a,b] [ a, b].
integration, the rst being that integration is in-verse to di erentiation. Besides that, a few rules can be identi ed: a constant rule, a power rule, linearity, and a limited few rules for trigonometric, logarithmic, and exponential functions.

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.
