Proof by infinite descent

ID: proof-by-infinite-descent

Proof by infinite descent is a mathematical proof technique that is particularly effective in certain areas, such as number theory. It is based on the principle that a statement is true if assuming its negation leads to an infinite sequence of cases that cannot exist in practice. The idea can be summarized as follows: 1. **Assumption of Negation**: Start by assuming that there exists a solution (or an example) that contradicts the statement you are trying to prove.
