If R and S are relations on a set A, then prove: R is reflexive and S is any relation implies RUS is reflexive.
Dear Abhingya
R is reflexive ==> for all x belonging to A....x is related to itself
As both relations R and S are defined on A..
R union S is reflexive ==>for all x belonging to A....x is related to itself......which is true as R is reflexive.
Hence R is reflexive and S is any relation implies RUS is reflexive.
