The general idea is to use trapezoids instead of rectangles to approximate the area under the graph of a function. A trapezoid looks like a rectangle except that it has a slanted line for a top. Working on the interval [a; b], we subdivide it into n subintervals of equal width h = (b a)=n.
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.

Approximate Integration: Trapezoid Rule and Simpson’s Rule There are two situations in which it is impossible to find the exact value of a definite integral. The first situation arises from the fact that in order to evaluate yb a fsxd dx using the Fundamental Theorem of Calculus we need to know an antiderivative of f. Sometimes,
for calculating definite integrals are: 1.Simpson’s rule, and 2.The trapezoidal rule. This module considers the trapezoidal rule. The Trapezoidal Rule The trapezoidal rule works by estimating the area under a graph by a series of trapezoidal strips. In the figure below, we see an approxima-tion to Z 6 1 xe 0.5xdx
