Unformatted text preview: that the actual points −→ p ( θ ) trace out the same curve as was already traced out for 0 < θ < π . The curve is shown in Figure 2.16 . In this case, we can Figure 2.16: The curve r = sin θ recover an equation in rectangular coordinates for our curve: multiplying both sides of r = sin θ by r , we obtain r 2 = r sin θ...
