# Squeeze Theorem*

The **squeeze theorem**** **is a theorem regarding the limit of a function.

It is also known as:

**pinching theorem****sandwich theorem****sandwich rule****squeeze lemma**

It is typically used to confirm the limit of a function via comparison with two other functions whose limits are known or easily computed.

Fun fact 1: It was first used geometrically in an effort to compute *π**.*

Fun fact 2: The squeeze theorem is also known as the **two policemen (and a drunk) theorem.**

- The story is that if two policemen are escorting an intoxicated prisoner between them, and both officers go to a cell, then (regardless of the path taken, and the fact that the prisoner may be wobbling about between the policemen) the prisoner must also end up in the cell.
