Chapter 1. Metric spaces - Proofs covered in class
Theorem 1.2 – Main facts about open sets 1 If X is a metric space, then both ∅and X are open in X. 2 Arbitrary unions of open sets are open. Proof. First, we prove 1.The definition of an open set is satisfied by every point in the empty set simply because there is no point in

The Fresnel Biprism - Trinity College Dublin
www.maths.tcd.ie2.2 The Fresnel Birpism A Fresnel Biprism is a variation on the Young’s Slits experiment. The Fresnel biprism consists of two thin prisms joint at their bases to form an isosceles triangle. A single wavefront impinges on both prisms; the left por-tion of the wavefront is refracted right while the right segment is refracted left.

sites.math.washington.eduHere are some basic subset proofs about set operations. Theorem For any sets A and B, A∩B ⊆ A. Proof: Let x ∈ A∩B. By definition of intersection, x ∈ A and x ∈ B. Thus, in particular, x ∈ A is true. Theorem For any sets A and B, B ⊆ A∪ B. Proof: Let x ∈ B. Thus, it is true that at least one of x ∈ A or x ∈ B is true.
