WebJun 12, 2016 · Then putting these values of θ in r = a(1 +sinθ), we get values of r as {a, 3a 2,2a, 3a 2,a, a 2,0, a 2,a}. As r = 0 is one of the points, it passes trough origin. Observe that values move in a cycle and hence the curve is a closed one. Further for each θ and corresponding π− θ value is same, hence the curve is symmetric around y -axis.
