Let S be the set of all real numbers. Then the relation R:- {(a ,b):1+a b >0} on S is: (a)an equivalence relation (b)Reflexive but not symmetric (c)Reflexive and transitive (d) Reflexive and symmetric but not transitive

If Z is the set of integers. Then, the relation R={(a,b):1+ab gt 0} on Z is

Let S be the set of all real numbers sjow that the relation R={(a,b):a^(2)+b^(2)=1} is symmetric but neither reflextive nor transitive .

Let S be the set of all real numbers. A relation R has been defined on S by a Rb rArr|a-b| le 1 , then R is

Let S be the set of all real numbers and let R be relation in S, defied by R={(a,b):aleb^(3)}. Show that R satisfies none reflexivity , symmetry and transitivity .

The relation R, in the set of real number defined as R = {(a,b): a lt b} is:

Let S be the set of real numbers. For a, b in S , relation R is defined by aRb iff |a-b|lt 1 then R is
