WebbThe Squeeze Theorem, also known as the Sandwich theorem, is a tool for determining the limits of trigonometric functions that have been supplied. The pinching theorem is another name for this particular theory. In calculus, as well as in mathematical analysis, the Sandwich theorem is frequently used to solve problems.
