Proof By Contradiction

Показать описание
The proof by contradiction is one of (if not the) most popular proof methods in mathematics. This video discusses the general logic for the proof and a few examples.

If you're in a rush, or just don't like waiting for information you need, I'd recommend speeding the video 1.5-2x and pausing whenever there's something you need clearing up.

I'd also recommend pausing the video before examples and trying them on your own - it might be tedious, but you'll retain the information you've learnt longer and gain a more in-depth understanding of the concept.
