Consider the following relations:
R1 = {(a, b) ?R2 ? a > b}, thegreater than relation
R2 = {(a, b) ?R2 ? a ? b}, thegreater than or equal to relation
R3 = {(a, b) ?R2 ? a < b}, theless than relation
R4 = {(a, b) ?R2 ? a ? b}, the lessthan or equal to relation
R5 = {(a, b) ?R2 ? a = b}, theequal to relation
R6 = {(a, b) ?R2 ? a ? b}, theunequal to relation
For these relations on the set of real numbers, find
R2?R1
R2?R2
R3?R5
R4?R1
R5?R3
R3?R6
R4?R6
R6?R6
