Sketch the graph of r= - 13 cos 50. The equation r= - 13 cos 50 is of the form r= a cos n0. Therefore, the graph is a rose. How many petals does the rose have? (Simplify your answer.) What is the length of each petal? unit(s) (Simplify your answer.) At what values of 0 do the endpoints of each petal occur? Since the value of n is odd, give values of 0 on the interval [0,x).
