Trapezoidal Rule for Integration (Definition, Formula, and …
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.

The trapezoidal rule formula is an integration rule used to calculate the area under a curve by dividing the curve into small trapezoids. Understand the trapezoidal rule formula along with its derivations, examples, and FAQs.
Trapezoidal rule - Wikipedia
In calculus, the trapezoidal rule (also known as the trapezoid rule or trapezium rule) [a] is a technique for numerical integration, i.e., approximating the definite integral: (). The trapezoidal rule works by approximating the region under the graph of the function f ( x ) {\displaystyle f(x)} as a trapezoid and calculating its area.
7.02: Trapezoidal Rule of Integration - Mathematics LibreTexts
2023年10月5日 · 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.
