## Trapezoidal Rule for Integration (Definition, Formula

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

## Numerical Integration Using the Trapezoidal Rule

The Trapezoidal Rule is an integral approximation technique that divides the area under the curve into little trapezoids and sums the area of each trapezoid together to approximate the total

## Trapezoidal Rule

As highlighted in the beginning, the trapezoidal rule is an approximate method to calculate the area under a curve/perform numerical integration. In the sample workbook, you

## Trapezoidal rule to estimate area under the curve

Trapezoidal Rule Formula Let f (x) be a continuous function on the interval [a, b]. Now divide the intervals [a, b] into n equal subintervals with each of width, Δx =
