Relations - A relation R is a non-empty sub-set of a cartesian product. A relation R is a non-empty sub-set of a cartesian product. A relation is a set of ordered pairs, i.e., R A x B where A and B are two non-empty sets. If R is a relation, write x R y or (x..

}. The defining sentence states the rule of the relation xRy. {(x, y) : x, y N x + y = 5} x + y = 5 is called the defining sentence. This relation can be expressed in roster form as {(1, 4), (2, 3), (3, 2), (4..
