The following relations are defined on the set of real number: `a R bifa-b >0` `a R bif1+a b >0` `a R bif|a|lt=b` Find whether these relations are reflexive, symmetric or transitive.

aRb if a-b>0 is defined on the set of real numbers,find whether it is reflexive, symmetric or transitive.

The following relations are defined on the set of real numbers. (i) a R b iff |a - b| gt 0 (ii) a R b iff |a| = |b| (iii) a R b iff |a| ge |b| (iv) a R b iff 1 + ab gt 0 (v) a R b iff |a| le b Find whether these relations are reflexive, symmetric or transitive.

aRb iff 1+ab>0 is defined on the set of real numbers,find whether it is reflexive, symmetric or transitive.

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

aRb if |a|<=b is defined on the set of real numbers,find whether it is reflexive, symmetric or transitive.
