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.
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. Assume that f (x) f ( x) is continuous on [a,b] [ a, b]. Let n be a positive integer and Δx= b−a n Δ x = b − a n. If [a,b] [ a, b] is divided into n n subintervals, each of length Δx Δ x, and mi m i is the midpoint of the i th subinterval, set. M n = n ∑ i=1f(mi)Δx M n = ∑ i = 1 n f ( m i) Δ x.
