Use the ezplot to graph the following parametric funtions:
(a) f1(t) = x =sin (t)
f2(t) = y =cos (t)
(b) f1(t) = x =sin (t)
f2(t) = y =3 cos (t)
(c) f1(t) = x = sin (t)
f2(t) = y = cos (3t)
(d) f1(t) = x = 10sin (t) from t = 0 to 30
f2(t) =y = t cos (t) From t = 0 to 30
(e) f1(t) = x = t sin (t) from t = 0 to 30
f2(t) = y = t cos(t) from t = 0 to 30
