Homework 1 Solutions - Montana State University
math.montana.eduHomework 1 Solutions 1.1.4 (a) Prove that A ⊆ B iff A∩B = A. Proof. First assume that A ⊆ B. If x ∈ A ∩ B, then x ∈ A and x ∈ B by definition, so in particular x ∈ A. This proves A ∩ B ⊆ A. Now if x ∈ A, then by assumption x ∈ B, too, so x ∈ A ∩ B. This proves A ⊆ A ∩ B. Together this implies A = A∩B.
