A trapezoidal number is a set of positive integers obtained by summing consecutively two or more positive integers greater than one, forming a trapezoidal pattern.

In order for a polygon to be a trapezoid, it must have the following properties: Four sides: A trapezoid is a four-sided polygon. Two parallel sides: A trapezoid has two sides that are parallel to each other. …

Jul 23, 2025 · The trapezoidal rule finds the area under the curve by dividing the area under the curve into various trapezoids and then finding the sum of all the trapezoids.

In mathematics, the trapezoidal rule, also known as the trapezoid rule or trapezium rule is a technique for approximating the definite integral in numerical analysis. The trapezoidal rule is an integration rule …

The meaning of TRAPEZOID is a quadrilateral having only two sides parallel.

Key idea: By using trapezoids (aka the "trapezoid rule") we can get more accurate approximations than by using rectangles (aka "Riemann sums"). Let's check it out by using three trapezoids to …
