Trapezoidal rule - Wikipedia
https://en.wikipedia.org/wiki/Trapezoidal_rule
The trapezoidal rule works by approximating the region under the graph of the function as a trapezoid and calculating its area. It follows that. An animation that shows what the trapezoidal rule is and how the error in approximation decreases as the step size decreases.

Trapezoidal Rule for Integration (Definition, Formula, and Examples)
https://byjus.com/maths/trapezoidal-rule/
Trapezoidal Rule is a rule that evaluates the area under the curves by dividing the total area into smaller trapezoids rather than using rectangles. This integration works by approximating the region under the graph of a function as a trapezoid, and it calculates the area.

Key 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] .

The trapezoidal rule is based on the Newton-Cotes formula that if one approximates the integrand by an \(n^{th}\) order polynomial, then the integral of the function is approximated by the integral of that \(n^{th}\) order polynomial. Integrating polynomials is simple and is based on the calculus formula.
