Use the definitions and properties discussed in class and chapter 9.1 and the properties or operations of irreflexive, asymmetric, inverse re- lations, and cornplernentary relations mientioned before Rosen 9.1 # 11 (p. 581), # 18 (p. 582) and # 26 (p, 582) Let R-(a, a), (b, c), (c, b), (c, d), (d, c), (d, d)], T = {(a, a), (a, b), (b, e), (b, d), (c, d), (d, a), (d, b), and U = {(a, a), (a, d), (b, c), (b, d), (c, a), (d, d)) 5.
