WebSuppose that: ∀ n ∈ N: y n ≤ x n ≤ z n. Then: x n → l as n → ∞. that is: lim n → ∞ x n = l. Thus, if x n is always between two other sequences that both converge to the same limit, x n is said to be sandwiched or squeezed between those two sequences and itself must therefore converge to that same limit . WebThe Squeeze Theorem As useful as the limit laws are, there are many limits which simply will not fall to these simple rules.

Proof squeeze theorem

The squeeze theorem is formally stated as follows. • The functions and are said to be lower and upper bounds (respectively) of . • Here, is not required to lie in the interior of . Indeed, if is an endpoint of , then the above limits are left- or right-hand limits. • A similar statement holds for infinite intervals: for example, if , then the conclusion holds, taking the limits as . WebThe squeeze theorem is used to evaluate a kind of limits. This is also known as the sandwich theorem. To evaluate a limit lim ₓ → ₐ f (x), we usually substitute x = a into f (x) and if that leads to an indeterminate form, then we apply some algebraic methods.
