A polar equation is given by r = 2 + 3 cos θ. (a) Show that the graph of the equation is symmetrical with respect to x-axis and passes through the origin. (b) Using information in (a), construct a table for appropriate value of r and θ and hence sketch the graph of r. (c) Find the points of intersection between the above graph and the graph r = 2.
