# Conversion Calculation Method of Multivariate Integrals:

The conversion calculation method of multivariate integrals is used to solve the problems in the two-dimension and three-dimensional planes. Now we have to understand the definite and indefinite integral. The definite integral has well-defined upper and lower limit boundaries, while the indefinite integral has no defined upper and lower limit boundaries. The triple integral calculator can be used to solve multivariable integral. These changes occur in a three-dimensional plane.

Now we try to understand the concept of the integral and its application in real life:

## Integral:

An integral is a function where we find the change by finding the derivation of the function. The Integral is also found by the anti-derivation of the function”. The anti-derivative is commonly known as the integration of the functions to find the integral or change of multivariable integral in 2D and three 3D planes.

Integrals are used to find the area of 2D objects and the volume of the three objects. We normally evaluate the triple integral, to find the volume of a 3D object.

## How We Use The Integral:

We use integral to find the area under a curve, the area is bounded by a curve. To find this area we normally use integration and derivation to solve the complex mathematical problems to solve the multivariable integral in the three-dimensional plane (x,y,z) and in the two-dimensional plane or cartesian plane (x,y) plane.

Integration and differentiation are key calculation methods to find the variation in multiple variables. For example, to find the volume of the cylinder in a three-dimensional plane, we can use the cylindrical integral calculator. This tool makes life easy as it takes a lot of integration to find the solution of three-dimensional change.

There are two main types of Integral in mathematics:

Definite integral

Indefinite integral

## Definite Integral:

When an integral has a starting value and an ending value, we call it a definite integral. The definite integral has upper and lower boundaries. The values of the function are restricted between the upper and the lower limits (a,b) of an interval. We can use an online triple integral calculator for the value of the definite integral.

Where “a” and “b” are upper and lower limits of the interval.

## Indefinite Integral:

The indefinite viable have no upper and limit, you can say there is an infinity tag is used to find the indefinite, we can predict the value of the indefinite variable at any point of time by putting the values in the equation of the indefinite variable. We can use an online triple integral calculator for the value of the indefinite integral.

## Application of The Integrals:

There are multiple applications of the integral in different fields:

## Use in Architecture:

By using the integral of multiple variables, we can find the material requirement in a curved surface like a dome, we can exactly calculate the amount of material required in a dome by using the triple integral calculator.

## In The Field of Electrical Engineering:

We can find the length of a power cable for making a transmission line between two power stations. An online triple integral calculator can be used to find the length of the cable.

In the field of medicine:

We can find the spread of diseases by the integral method, how quickly the disease is going to spread, the origin of the disease, this can be great to eradicate the infectious diseases.

### In statistics:

In stat, the projections of the integral can be used to estimate the result of the survey and to determine the possible outcome of a projection. The surveys are important to know the demographic of an area. Companies conduct a survey to know the needs and wants of a marketplace. The projections can be calculated by the triple integral calculator.
