Instructions for using the Double Integral Calculator

As you can see, the calculator has a very intuitive interface which makes it easy to use. To use it, you just have to follow the following steps:

  1. Choose the type of coordinates you will use to compute the double integral: Choose the "Rectangular" option to compute double integrals over rectangular regions, or select the "Polar" option to compute double integrals in polar coordinates.
  2. Select the differential of integration: if you have selected rectangular coordinates you have two drop-down lists to do so. In the case that you have selected polar coordinates, the integration differential will be rdrdt, where the variable t refers to the Greek letter theta.
  3. Enter into the calculator the function that will be the integrand of the double integral. To do this, keep in mind the table of valid functions presented in this section.
  4. Then enter the limits of integration, which can be numeric or mathematical expressions that use the variables present in the differential of integration. Note that to enter the number pi, you must write pi and if you want to write ∞ you must write inf.
  5. Select the decimal places of precision.
  6. Finally press the "Calculate" button to get the result. The solution will be deployed automatically showing the steps of the integration process.

For examples of double integrals you can press the "Examples" button.

What is a Double Integral?

Double integrals are commonly used in physics, engineering, and other fields to solve problems involving the distribution of quantities over a region in two-dimensional space. For example, a double integral can be used to calculate the mass of an object by integrating its density over the volume of the object.

Properties of Double Integral

The double integral is linear

The double integral is additive

Consequently, if f(x,y)≥0 at almost all points in R,

and if f(x,y)≤0 at almost all points of R,
