cos? 0, 0 < 0 < 27 (solid), along with the point P corresponding to 0 = T/6, and the tangent line l to the curve at P (dashed). The curve is symmetric about both axes. Shown below is the polar curve r = (a) (2 points) Find polar coordinates for P. (b) (3 points) Find the Cartesian coordinates of P. (c) (4 points) Find the slope of l. (d) (4 points) Set up an integral that represents the area enclosed by the curve. Do not evaluate the integral. You may use symmetry.
