This exercise is about curves represented by parametric equations. The parametric curve with coordinates (as, 3;) given by a: = cos(8t) cos(t), y = 605(8t) 51116) for 0 S t S 7, has a beautiful shape that looks like a flower. Use demos (or another graphing calculator) to plot this parametric curve. How many petals does the ower-shaped graph have? Count them and type the number of "petals" of the graph
