# How to find definite and indefinite integrals (Step-by-Step):

In calculus, we need to find the derivative of a function to find a real-time solution, the inverse of derivation is the integration. You can see the implementation of derivation and integration ins solving most problems in the calculus, These are used to find the maximum and minimum values of a function, you can use an integral calculator to find the result of various functions, it can be solved in steps, so you can understand the procedure of integration by integral calculator with steps.

This can be great for engineering and mathematics students, to solve the lengthy problem, as they need to know the result of integration to use it further in the solution of the questions. You can also solve various parts of the integration by integration by parts calculator, so make it easy for you to understand various parts of the integral, no matter how long the procedure is, it can solve the integral for you in parts.

We can use the integral calculator for the graphical solution of integration of functions. These integration tools are simple to use and perfect for the integration of all types of functions.

When we study the integration, we come to find there are two types of integral:

• Definite Integral
• Indefinite integral

## Definite integral:

The definite integral is an integral having a lower and upper limit and represent an area under the curve f(x) for x=a to x=b, we can write the definite integral as:

abf(x)dx

Where f(b) is considered as the upper limit of the integration and f(a) is considered as the lower limit of the integration, we can find a solution of number by putting the upper and lower limit values to the definite integral, You can use the definite integral calculator to find the integral of a definite integral.  You need to enter both the upper and lower limit to find the integral solution.

## Indefinite integral:

The indefinite integral is written without upper and lower limits, and we call it indefinite as it has no limit or boundaries. If we had a function at the end of the integration, the answer would have a function that still has an “x” song with a constant “c” as the answer.

We can write the indefinite integral as follows:

f(x)dx

There are no upper and lower limits of  the indefinite integral and we can write the answer as:

f‘(x)+c

Where “c” is an arbitrary constant value,

For example, if we need to write the indefinite integral of a function given, then we can write it as follows:

x3dx= 14x4+c

We can use an indefinite integral calculator to solve an indefinite integral, we use various steps to solve an integration process, simplify the question, and apply the limits if it is a definite integral.

## How to find definite integral:

Now when we have to evaluate the definite integral, we have to consider the lower and the upper limit, consider the following definite integral, we solve it step by step:

f(x)= 23y3dy

• Graphically, we are finding the area under the curve f(x)=y3between y=2, and y=3.
• In the first step, we will find the integral of the function f(x)=y3and then put the values of lower and the upper limits in the integral.
• Now when computing the integral we found:

The integral in this case is:

y44

• Now we have to put the upper and lower limits for y=2, and y=3, in this integral

344244=654

• We put the values of the upper and the lower limits of the integral in the expression, and do not use the value of the constant in the definite integral, we can use the definite integral calculator to solve the above expression.

## How to find indefinite integral:

Now when we have to evaluate the indefinite integral, In this case, there are no lower and the upper limit as it is indefinite integral, consider the following indefinite integral, we solve it step by step:

f(x)= y3dy

• Graphically, we are finding the area under the curve f(x)=y3of indefinite area.
• In the first step we will find the integral of the function  f(x)=y3Now when compute the integral we found:

y44+C

• Where “C” is a constant and is used as an indefinite integral, we solve the indefinite integral by using an indefinite integral calculator, we can solve the indefinite integral step by step.

### Fundamental Theorem of Calculus:

We use the fundamental Theorem of Calculus to solve the definite and indefinite integral, according to the Theorem, we use the same method, but in the definite integral, we put the value of the lower and the upper limits after computing the integral. We can use the integration calculator to solve an integral, the tool like an integral solver is best to solve an integral step by step, but students do need to understand the basic procedure of the integration and now the integral of the trigonometric function.

### Integration of the trigonometric ratios:

For the integration of the trigonometric ratios, you need to remember the basic conversions of the trigonometric ratios. You can’t understand the integral conversion by an integral calculator if you don’t have the basic knowledge of the trigonometric conversion:

So it is critical to remember the basic formula of trigonometry

• tanx =SinxCosx
• secx= 1Cosx
• cotx= 1tanx=CosxSinx
• cscx= 1Sinx

These kinds of trigonometry and others involved in the interaction process, for doing integration, students should have familiarity with them, otherwise, they can’t understand the definite and indefinite integration of the trigonometric functions. Even if you are using the Double integral calculator by https://calculator-online.net/double-integral-calculator/, the main reason for that, the conversion is done and then you apply the limits, which can be quite confusing for the students. This is the main reason why students find integration a little difficult to solve. The integration process of the trigonometric ratio is most difficult to understand.
