Skills Find parametric equations for each of the vector-valued func- tions in Exercises 26-34, and sketch the graphs of the func- tions, indicating the direction for increasing values of t. 26. r(t) - (sin 3t, cos 3t) for t e [0, 2x ] 27. r(t) = (2 - sint, 4 + cost) for t e [0, 2x ] 28. r(t) = (sint, cos 2t) for t = [0, 2x] 29. r(t) = (1 + sint, 3 - cos 2t) for t e [0, 27 ] 30. r(t) = (3 + ti + (3 - -) j fort = 0 31. r(t) = (t, +2, +3) for t = [0, 2] 32. r(t) = (cos2 +, 4 sint, t) for t = [0, 2x ] 33. "(t) = (cos2 t, sin 2t) for t = [0, 2x]
