WebSo the usual explanation for dA in polar coords is that the area covered by a small angle change is the arc length covered times a small radius "height". The arc length covered is r * dTheta, and the "height" is dr, so dA is r (dr) (dtheta), where r … Webconnection dA=dxdy. dxdy is the area of an infinitesimal rectangle between x and x+dx and y and y+dy. In polar coordinates, dA=rd(theta)dr is the area of an See the figure below. The area of the region is the product of the length of the region in theta direction and the width in the r The width is dr.
