Use a graphing utility to graph the curve represented by the parametric equations. (Indicate the orientation of the curve.) Hypocycloid: x = 6 cos³ (0), y = 6 sin³ (0) Identify any points at which the curve is not smooth. (Use n as an arbitrary integer. If an answer does not exist, enter DNE.) 0 = || ×

A baseball is hit at a point 3 feet above the ground toward the left field fence. The fence is 10 feet high and 375 feet from home plate. The path of the baseball can be modeled by the parametric equations x=115cost and y=3+115sint16t2. Does the baseball go over the fence when it is hit at an angle of =30 ? Does the baseball go over the fence when =35 ?
