The symmetric difference is equivalent to the union of both relative complements, that is: = (), The symmetric difference can also be expressed using the XOR operation ⊕ on the predicates describing the two sets in set-builder notation: = {: ()}. The union of two sets A and B is the set of elements which are in A, in B, or in both A and B. Symmetric difference between two sets is a set of elements that are in both sets but not in their intersection. The symmetric difference of two sets A and B is the set of elements that are in either A or B, but not in their intersection. To stress this point, with just a little work we will see the symmetry of the symmetric difference since we see A ∆ B = (A – B ) ∪ (B – A) = (B – A) ∪ (A – B ) = B ∆ A. Courtney K.
