How to Apply Trapezoidal Rule?

- Step 1: Note down the number of sub-intervals, “n” and intervals “a” and “b”.
- Step 2: Apply the formula to calculate the sub-interval width, h (or) △x = (b – a)/n.
- Step 3: Substitute the obtained values in the trapezoidal rule formula to find the approximate area of the given curve,

### What is the formula of trapezoidal rule?

The Trapezoidal Rule T n = 1 2 Δ x ( f ( x 0 ) + 2 f ( x 1 ) + 2 f ( x 2 ) + ⋯ + 2 f ( x n − 1 ) + f ( x n ) ) .

#### How do you find the area under a trapezoidal rule?

Trapezoidal rule approximates area under the curve With this method, we divide the given interval into n subintervals, and then find the width of the subintervals. We call the width Δx. The larger the value of n, the smaller the value of Δx, and the more accurate our final answer.

**How do you use the trapezoidal rule on a calculator?**

How to Use the Trapezoid Rule Calculator?

- Step 1: Enter the function, interval and limits in the input field.
- Step 2: Now click the button “Submit” to get the area.
- Step 3: Finally, the area under the curve using the trapezoid rule will be displayed in the new window.

**How does trapezoidal rule work?**

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.

## What is the difference between trapezoidal rule and composite trapezoidal rule?
