## Introduction to Area Under the Curve Calculator:

Area under the curve calculator is a tool that is used to find the solution of **area between a given curve**. It evaluates the area that is enclosed under the closed curve within the x-axis in a specific interval.

It is a beneficial tool that helps you in the calculation of area under the curve problems and provides you an accurate solution as it is used in various fields like mathematics, statistics, physics and many other fields as well.

## What is the Area Under the Curve?

Area under the curve is a process of the **total area enclosed** between a given curve along the x-axis within a specified interval. This method is used in various fields, such as calculus, statistics, physics, and it is also used to quantify the accumulated values which are represented by the curve.

In calculus, the area under the curve y=f(x) from x=a to x=b is determined using the definite integral.

$$ Area \;=\; \int_a^b f(x) dx $$

This integral sums the small areas under the curve over the interval [a,b]. The definite integral can be interpreted as the limit of a sum of the areas of rectangles under the curve as their widths approach zero.

## How to Calculate the Area Under the Curve?

The area under the curve method is used to **calculate the total area** that is present inside the curve in a bounded region. To calculate the total area in seconds, you can use our area under curve calculator. If you prefer manual calculation, you can explore the calculation steps provided below.

**Step 1**: Identify the given function f(x) and Interval [a,b] over which you want to find the area under the curve.

### Example: Consider f(x) = x^{2} and the interval [0,2].

**Solution**:

**Step 2: **The area under the curve is y= f(x) from x=a to x=b, the upper and the lower interval by the definite integral,

$$ Area \;=\; \int_a^b f(x) dx $$

$$ a \;=\; 0,\; b \;=\; 2 \;and\; f(x) \;=\; x^2 $$

**Step 3**: Put the function value and limit value in the given formula of the area under the curve to compute the definite integral of the function f(x).

For,

$$ f(x) \;=\; x^2,\; a \;=\; 0,\; b \;=\; 2 $$

$$ \int_0^2 x^2 dx $$

**Step 4**: Then evaluate the antiderivative function F(x) and apply the upper and lower limits of the integral, b and a:

$$ Area \;=\; \frac{x^3}{3} $$

$$ Area \;=\; \frac{x^3}{3} \biggr|_0^2 \;=\; \frac{3^2}{3} - \frac{3^0}{3} $$

$$ =\; \frac{3}{8} - 0 $$

$$ =\; \frac{3}{8} $$
