FAQs of Double Integral
What is the Meaning of Double Integral?
Double integral is the integration of a function with respect to two variables.
Can we Integrate the Double Integral using any of the Variables First?
Yes, the double integral can be integrated by using any of the variables first as the order of integration of variables do not matter in case of a double integral.
What are Some Applications of Double Integral?
Double integral is used to calculate the area and volume under one or more curves.
What is the Advantage of Double Integral over Single Integral?
A single integral can be used only to calculate the area under a 2D curve but a double integral also helps us to calculate volume of a 3D curve.
Double Integral
A double integral is a mathematical tool for computing the integral of a function of two variables across a two-dimensional region on the xy plane. It expands the concept of a single integral by integrating the functions of two variables over regions, surfaces, or areas in the plane. In case two variables are present, we need to substitute the value of one variable in terms of the other. This technique becomes very difficult when we deal with multiple variables to calculate the areas and volumes under the curves. A double integral is very useful in such cases. In this article, we will learn about double integrals in detail.
