**How can I solve Integrations Easily?**

An integral is a numerical value that shows the area under the graph for a specific interval or function. In mathematics, It assigns numerical values to the functions so that they can represent the area, volume, displacement and other concepts.

Lets take a look at the following types of integrals:

**Definite Integrals:**

An integral in which the upper and lower limits are defined is known as the definite integral. Here upper and lower limits are the start and end points.

**Indefinite Integrals:**

The integrals that are not defined are known as the indefinite integrals. They basically show the given function which is the derivative f and in return, it provides a function of the independent variable.

Instead of performing the complex calculation for solving the integral you can easily visit calculatored.com and get the help of an online integral calculator. This online calculator allows users to calculate the integrals without installing any additional software on your smart device.

**How to Calculate Integral?**

The solution of integral requires the users to go through a step-by-step procedure. This calculation can be very annoying and time taking for beginners. However to solve the integrals check out the following example:

**Example:**

For function f(x) = x – 1, calculate the definite integral if the given interval is [2, 8].

**Solution:**

Write down the function F(x).

F (x) = x – 1.

Interval = [2, 8].

Now by evaluating the integral of the function.

∫ (x−1) dx = (x^{2}/2) – x + C.

As, a = 2, and b = 8,

F(a) = F(2) = (2^{2}/2) – 1 = 1.

F(b) = F(8) = (8^{2}/2) – 10 = 22.

The difference between the upper limit F(a) and lower limit F(b) of the integral.

F (b) – F (a) = 22 – (1) = 21.
