"WebbThe squeeze theorem (also called the sandwich theorem or pinching theorem ), is a way to find the limit of one function if we know the limits of two functions it is “sandwiched” between. It can be a little challenging to find the functions to use as a “sandwich”, so it’s usually used after all other options like properties of limits ... " - The pinching theorem
