Unformatted text preview: R . Your sketches in Question.2 may be helpful. (a) R is one leaf of the curve r = sin(3 θ ). (b) R is bounded by the curve r = 1-cos θ . (c) R is the region inside the larger loop and outside the smaller loop of the curve r = 1 + 2 cos θ . 5. In parts (a)–(b), ﬁnd the lengths of the polar curves. (a) r = e aθ ,-π ≤ θ ≤ π (b) r = a (1 + cos θ ) , ≤ θ ≤ 2 π...
