How to Use Double Integral Calculator with Steps?

Following are the complete steps and guidance about how this calculator works. Simply by following these simple steps one can easily get the double integrals.

You have to choose the integrals which you want to integrate and also choose the integral function from the list.
Now you have to select either definite or indefinite integrals.
Definite integral solver- if you know about the limits i.e., upper bound or lower bound, then you should go for the definite integrals.
Indefinite integral solver- but if you don’t know about the limits or you don’t have limits then go for the indefinite option.
After substituting the data in the required fields, you can just click the "CALCULATE" button.
In a few seconds the result is blinking on your device’s screen.

Formula Used by Double Integral Solver

A double integral is typically calculated using the following formula:

formula used by double integral calculator

where f(x,y) is the function being integrated with respect to x and y, and the limits of integration are specified by the integral signs. The integral is calculated by first performing the inner integral with respect to one variable, and then performing the outer integral with respect to the other variable. The result of the double integral is a scalar value.

You can use a multiple integral calculator to evaluate double integral for specific limits and function. But for the calculation of improper integrals, you need to try our convergent or divergent calculator online.

Let's get a brief understand of double integration by looking up the below example:

Example: Evaluate double integral (x³+y³)dxdy or ∫∫(x³+y³)dxdy

Solution: Let us say, I = ∫∫(x³+y³)dxdy

$$ I \;=\; ∫[∫(x^3 +y^3)dx]dy $$ $$ I \;=\; ∫[ \frac{x^4}{4} + y^3x]dy $$ $$ I \;=\; \frac{x^4y}{4} + \frac{xy^4}{4} $$ $$ I \;=\; \frac{[xy (x^3+y^3)]}{4} + c $$

So, in this way our integral calculator solves integrals with step by step solution.

What Does the Double Integral Represent

The double integral represents the volume of the function on a defined region in the two-dimensional plane. If the function represents the three-dimensional surface then the double integral determines the volume beneath the surface.

If the function is constant then the double integral online calculates the area of the region in the xy plane that is often used to determine the area of complex shapes bounded by the curves.

Double integrals can calculate the physical quantities such as charge, mass, or the moment of inertia when it is defined in the two-dimensional plane.

In vector calculus, the double integrals represent the flux through a surface where integrals help to accumulate the quantity on the region defined by the boundary.

Why Do we Use Double Integrals?

Double integrals are an important field in mathematics, physics, engineering, and other fields as they give a way to calculate the variety of properties on two-dimensional regions. So here are some points that will explain why to use double integrals,

Double integrals help in calculating the area of a region in volume under a surface and plane. This is useful for irregular or curved regions where the traditional formula is inadequate.
Double integral represents the properties of surfaces or the two-dimensional fields that help to understand and analyze the behavior such as calculating the centroid of a shape and finding the total across a surface and calculating the surface area of a 3D object.
Double integrals help in statistics and probability which are important to calculate the averages, expectations, and joint probabilities.
Double integrals also help in engineering and physics to calculate the physical quantities such as charge, mass, or moment of inertia.

What is Double Integration Method

Double integration is a method that is used to integrate the functions on a two-dimensional region. This method involves calculating the integral in two stages with respect to two variables such as x and y. This method is also used by the double integration method calculator. Here are some steps of the double integration method,

First of all, identify the function that is to be integrated and find the region of integration to establish the integration limits.
Now choose the order of integration and set the inner and outer integration limits.
Represent the integral in the chosen order
Hold the constant of the outer variable and the integration of the inner variable
Now use the results of the inner integral to integrate with respect to the outer variable.

What are Some Reasons for Switching the Order of Integration Double Integrals

Switching the order of integration in the double integrals is a wonderful technique for different reasons. Some of the reasons include simplifying the integrals or resolving issues with integration limits, etc. which you can calculate better if you use the double integral graph calculator.

However, we have given some key reasons for switching the order of integration that are given below,

In some scenarios, the original integration limits may be difficult to integrate. So, by switching the order of integration you can find the simpler limits that make the integration process easier.
Switching the order of integration allows to avoid problematic regions such as function being integrated has discontinuities or undefined regions within the original limits etc.
In some scenarios, the different coordinate system such as polar, cylindrical, or spherical coordinates aligns better when there is a switching of order of integrations.
Switching the order of integration, you may get a form that is more suitable for numerical computations that enables more accurate results and vice versa.
