WebWe say the sets A and B are equal if and only if A ⊆ B and B ⊆ A, that is, ∀ x ( x ∈ A ⇔ x ∈ B). So to show two sets are equal one must verify that a biconditional is satisfied, which often needs to be done in two parts, that is, the easiest way to show that A = B often is to show that A ⊆ B and B ⊆ A. WebIf set A is a subset of set B, then the union of the two sets is set B. Using set notation: if A ⊆ B, then A ∪ B = B. For example, if A = {2n n ∈ ℕ} and B is the set of integers, then A …
