WebSep 22, 2016 · Prove the Squeeze Theorem (for limits of sequences). Given: ( a n), ( b n), and ( c n) are sequences, with a n ≤ b n ≤ c n for all n. Also, a n → a and c n → a. Prove by contradiction: ( b n) converges and b n → a. Here is my attempt. Please let me know if this is a viable proof, and how I can improve upon it.

Let Mn be a compact smooth manifold with a C Riemannian metric g. Fix a point o 2 Mf and de–ne, for x 2 Mf the function ˘ x (z) on Mf by: ˘ x (z) = d(x;z) d(x;o): The ... In calculus, the squeeze theorem (also known as the sandwich theorem, among other names ) is a theorem regarding the limit of a function that is trapped between two other functions. The squeeze theorem is used in calculus and mathematical analysis, typically to confirm the limit of a function via comparison with two other functions whose limits are known. It was first used geometrically by the mathematicians Archimedes and Eudoxus in an effort to compute π, and was …
