This calculator can function with the help of some simple clicks. The integral function is very easy to use and can be easily understood. The steps mentioned here are very understandable.

It gives the proper results after doing calculations. It will help you find the integrals step by step and make them easier to learn. The best property of integral solver with steps is that it is free of cost, easy to use, and gives you accurate results.

## What is Online Integral Calculator with Steps?

The word integral is used in integration to designate a number to a function. The word integral is belonging to the integration of calculus. The integral is a function, whose derivative is its function. Finding areas of any two-dimensional objects or the volumes of three-dimensional objects. So, it is stated as finding the integrals of any function concerning the y-axis means finding the area concerning the y-axis and vice versa.

The general integrals calculator does the same job. It **evaluates the integral function** to give you the results accurately and quickly. By doing some smart clicks one can get the required results. It also designates a number to a function which is known as an integral.

On the other hand, the integral of complex function is called integration by partial fraction which we may calculate with partial fraction integration calculator.

### Notation of Integral

The sign used to show integral is;

**∫**, This sign shows the integral of integration.

## Formula used by the best integral calculator is:

The general formula for evaluating the integral is: $$ \int f'(x) dx \;=\; f(x) + C $$

Here,

**f** is the integral function

**C** is constant.

In case, if two different functions are multiplying under the integral, use by parts integration calculator which uses the formula of special method of integration.

let's take a look how the online integration calculator with steps use this formula to solve integration.

**Example # 1:** Consider we have a function:

$$ \int_0^4 3x dx $$

**Solution:**

$$ \int_0^4 3x dx \;=\; 3 \int_0^4 x dx $$ $$ \int_0^4 3x dx \;=\; 3 \Biggr| \frac{x^2}{2} \Biggr|_0^4 $$ $$ \int_0^4 3x dx \;=\; 3 \Biggr[ \frac{4^2}{2} \;-\; \frac{0^2}{2} \Biggr] $$ $$ \int_0^4 3x dx \;=\; 40 $$

**Example # 2:** Consider we have a function:

$$ \int (5x^2 + 9) dx $$

**Solution:**

$$ \int (5x^2 + 9) dx \;=\; \int 5x^2 dx \;+\; \int 9 dx $$ $$ \int (5x^2 + 9) dx \;=\; 5 \frac{x^3}{3} \;+\; 9x $$ $$ \int (5x^2 + 9) dx \;=\; \frac{5x^3}{3} \;+\; 9x \;+\; C $$

**Related:** To calculate the integral of an integral, use of double integral calculator with steps is a best choice.
