WebThe student earned 3 points: no points in part (a), 1 point in part (b), no points in part (c), and 2 points in part (d). In part (a) the student does not square the integrand, so the integrand point was not earned. Because this is not a valid integrand for polar area, the student is not eligible for the limits and answer points.
