WebYou might be tempted to replace \redE {dA} dA with d\theta\,dr dθdr, since in cartesian coordinates we replace it with dx\,dy dxdy. But this is not correct! Remember what a double integral is doing: It chops up the region that we are integrating over into tiny pieces, and \redE {dA} dA represents the area of each one of those pieces.

WebOct 19, 2024 · 1 Answer. Sorted by: 4. In a double integral ∬ D f ( x, y) d A = ∬ D f ( x, y) d x d y, the symbol d A is just shorthand for the area element d x d y, “a little piece of area”. That's something completely different from the differential d A = y d x + x d y of the function A ( x, y) = x y! So there's no contradiction, just the same ...
