You suppose the claim is false, and you derive a contradiction, such as that 1 = 0 or that the same statement is both true and false. Since that is impossible, you must have been wrong when you supposed the claim was false; hence the claim is true! great expectations 2012 izle

"WebProof: Let ( a n) be a Cauchy sequence in ( S, d). Then each a n ∈ E since S ⊆ E, so we may treat ( a n) as a sequence in ( E, d). By completeness of ( E, d), a n → a for some point a ∈ E. Since S is closed, S contains all of its limit points, implying that any convergent sequence of points of S must converge to a point of S. " - Proof in math
