webKey idea: By using trapezoids (aka the "trapezoid rule") we can get more accurate approximations than by using rectangles (aka "Riemann sums"). An example of the trapezoid rule. Let's check it out by using three trapezoids to approximate the area under the function f ( x) = 3 ln ( x) on the interval [ 2, 8] .

Trapezoidal rule to estimate area under the curve
https://www.kristakingmath.com/blog/trapezoidal-rule
webMay 25, 2020 · The trapezoidal rule is one method we can use to approximate the area under a function over a given interval. If it’s difficult to find area exactly using an integral, we can use trapezoidal rule instead to estimate the integral. It’s called trapezoidal rule because we use trapezoids to estimate the area under the curve.

webThe Trapezoidal Rule. We can also approximate the value of a definite integral by using trapezoids rather than rectangles. In Figure 2, the area beneath the curve is approximated by trapezoids rather than by rectangles. Figure 2. Trapezoids may be used to approximate the area under a curve, hence approximating the definite integral.

webThe trapezoid rule uses the average between points to approximate the line the graph makes between the two points. Simpson's rule uses a quadratic parabolic arc. Simpson's is usually more accurate and quicker computationally than the trapezoid rule since it converges faster - that is, it gives a better result with fewer subdivisions because it ...
