Proof by exhaustion, also known as proof by cases, proof by case analysis, complete induction or the brute force method, is a method of mathematical proof in which the statement to be proved is split into a finite number of cases or sets of equivalent cases, and where each type of case is checked to see if the proposition in question holds. This is a method of direct proof. A proof by exhaustion typically contains two stages: WebFeb 24, 2024 · Most would say "no". However, you can also "unpack" this proof to prove any case. For example, if you need to know a number between $3.14$ and $3.141$, the proof shows you can take $3.1405$. You can do this for any case! But this is not a proof by exhaustion.
