Let R = {(x,y): |x2 – y2| < 1} be a relation on set A = {1, 2, 3, 4, 5}. Write R as a set of ordered pairs.

Given a relation R = {(x,y): |x2 – y2| < 1} on set A = {1, 2, 3, 4, 5}.


Now according to the condition |x2 – y2| < 1 .


x2 – y2 = 0


Describing R as set of ordered pairs:


R={(1,1),(2,2),(3,3),(4,4),(5,5)}
