(a) Investigate for asymptotes, Cf. § 79. (/>) Investigate for maximum and minimum points. Cf. § 112.(V) Investigate for points of inflexion. Cf. § 131.(d) Investigate for direction of curvature. Cf. § 130. EXAMPLES.1. Trace the curve r = a sin 3 6. r = o, when 0 = o°, 0 = 6o°, 0 = 1200, $ = 1800, etc.; hence, the curve repeatedly passes through the origin. r = a (a maximum value, since sin 3 0 cannot exceed unity)when 0 = 300, 0 = 1500. 6 = 2700. r = — a, a minimum value, when # = —30°, 0 = —1500, 0=-27O°. As 6 increases from o° to 300, r increases from o to a as 6increases from 3
