## Introduction

The Second Fundamental Theorem of Calculus is a powerful concept in mathematics that provides a connection between definite integrals and antiderivatives. Understanding and applying this theorem can be complex, but with the Second Fundamental Theorem of Calculus Calculator, the process becomes much more accessible. This tool is designed to assist students, professionals, and enthusiasts in efficiently evaluating definite integrals and solving problems related to the fundamental theorem.

## Formula:

The Second Fundamental Theorem of Calculus states that if $f(x)$ is a continuous real-valued function on the closed interval $[a,b]$ and $F(x)$ is an antiderivative of $f(x)$ on $[a,b]$, then:

$∫_{a}f(x)dx=F(b)−F(a)$

This formula establishes a link between the definite integral of a function and the difference between the antiderivative evaluated at the upper and lower bounds.

## How to Use?

Utilizing the Second Fundamental Theorem of Calculus Calculator is a straightforward process:

**Input Function**: Enter the function $f(x)$ for which you want to evaluate the definite integral.**Specify Bounds**: Define the upper and lower bounds, $a$ and $b$, for the definite integral.**Calculate**: Press the calculate button to obtain the result of the definite integral using the Second Fundamental Theorem of Calculus.

## Example:

Consider the function $f(x)=2x$ over the interval $[1,3]$. According to the Second Fundamental Theorem of Calculus:

$∫_{1}2xdx=F(3)−F(1)$

If $F(x)$ is the antiderivative of $f(x)$, such as $F(x)=x_{2}+C$ where $C$ is the constant of integration, then:

$∫_{1}2xdx=(_{2}+C)−(_{2}+C)=8$

So, the result of the definite integral is 8.

## FAQs?
