Please ignore this thread (problems with Latex and the question looks like a jumbled mess!)

- Area Double integral Integral
In summary, a double integral is a mathematical tool used to calculate the area under a two-dimensional surface or region. It is an extension of a single integral and is represented by two nested integrals. It can be used to calculate the area of any two-dimensional region, but the region must be bounded by two functions in the x and y directions. There are two types of double integrals - definite and indefinite - which are used for specific and general calculations, respectively. Double integrals have practical applications in various fields such as physics, engineering, and economics.

Hi PhysDrew! 
There's a LaTeX preview page (which Borek told me about) at https://www.physicsforums.com/mathjax/test/preview.html"

Nice one thanks for that!
Related to Double integral to calculate area
What is a double integral?
A double integral is a mathematical tool used to calculate the area under a two-dimensional surface or region. It is an extension of a single integral, which is used to calculate the area under a one-dimensional curve.
How is a double integral used to calculate area?
A double integral is typically represented by two nested integrals, where the inner integral is integrated with respect to one variable while the outer integral is integrated with respect to the other variable. This allows us to calculate the area of a two-dimensional region by breaking it down into smaller, simpler pieces.
What types of regions can be calculated using a double integral?
A double integral can be used to calculate the area of any two-dimensional region, including rectangles, triangles, circles, and more complex shapes. However, the region must be bounded by two functions in the x and y directions in order to be calculated using a double integral.
What is the difference between a definite and indefinite double integral?
A definite double integral is used to calculate the exact area of a specific region, while an indefinite double integral is used to calculate the general formula for the area of a region. The bounds of a definite integral are defined, while the bounds of an indefinite integral are left as variables.
Are there any practical applications of double integrals?
Double integrals have a wide range of practical applications in fields such as physics, engineering, economics, and more. They can be used to calculate the volume of a three-dimensional object, as well as to calculate the average value of a function over a given region.
