The Trapezoidal Rule Calculator is a free online tool that displays the area under the curve. This easy-to-use calculator makes the calculation faster and displays the area under the curve within a couple of seconds.

In traditional mathematics, the trapezoid rule is the rule that is used to determine the area under the curve. In this method, the area under the curve is derived by dividing the total area into much smaller trapezoids instead of dividing into rectangles as a whole.

In fact, the integration method works by approximating the area that lies under the graph of a function as a trapezoid and that is how it calculates the area. It gives a better approximation result though.

So, in simple words, the trapezoid rule is a numerical method used to approximate the definite integral.

The procedure to use the trapezoidal rule calculator is given as:

Step 1: First, enter the function, interval and limits in the input field.

Step 2: Then, you need to click the button “Submit” to get the area.

Step 3: Finally, the area under the curve using the trapezoidal rule will be displayed in the new tab.
