Question

if you have a parametric equation grapher, graph the equations over the given intervals

a. x = 6 cos t + 5 cos 3t, y = 6 sin t - 5 sin 3t; 0<=t<= 2pai

b. x = 6 cos 2t + 5 cos 6t, y = 6 sin 2t - 5 sin 6t; 0<=t<= pai

c. x = 6 cos t + 5 cos 3t, y = 6 sin 2t - 5 sin 3t; 0<=t<=2pai

d. x = 6 cos 2t + 5 cos 6t, y = 6 sin 4t - 5 sin 6t; 0<=t<=pai
