The Squeeze theorem allows us to compute the limit of a difficult function by “squeezing” it between two easy functions.

In mathematics, sometimes we can study complex functions by relating them for simpler functions. The Squeeze Theorem tells us one situation where this is possible.
I’m thinking of a function $f$. I know that for all $x$ What is $\lim _{x\to 0} f(x)$?
$f(x)$ $f(0)$ $0$ impossible to say

When solving a problem with the Squeeze Theorem, one must write a sort of mathematical poem. You have to tell your friendly reader exactly which functions you are using to “squeeze-out” your limit.
