WebMay 12, 2024 · 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 … 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 …
