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 ...

Solution 2 If a circle has radius r, then an arc of α radians has length r α. So with an infinitesimal increment d θ of the angle, the length is the infinitesimal r d θ. And the arc is a right angles to the radius, which changes by the infinitesimal amount d r. So the infinitesimal area involved is just the product r d r d θ. little auction service coffeyville ks
