Скачать или смотреть Proof by Contradiction | Method & First Example

Proof by Contradiction is one of the most important proof methods. It is an indirect proof technique that works like this: You want to show a statement P is true. First assume the P is actually false. Then manipulate until you get a contradiction like 0=1. This means your assumption that P was false is incorrect and so P is true. QED.

In this video we'll talk about the structure of proof by contradiction, and then do a small example where we prove a theorem that no integer is both even and odd.
