Two exercises in proving VALIDITY and ENTAILMENT using TRUTH TREES - Logic
We do two exercises in truth trees proving that a group of wffs entails another wff. Another way of saying that is that the argument is valid. 0:00 [Intro] 0:19 [Question #1] 4:38 [Question #2] 7:07 [Going Forward] Follow along in the Logic playlist: https://www.youtube.com/playlist?list

TAUTOLOGIES, CONTRADICTIONS, and CONTINGENT WFFS - Logic
In this video on #Logic / #PhilosophicalLogic, we learn about tautologies (wffs which are always true), contradictions (wffs which are always false), and contingent wffs (wffs which are both true and false depending on the situation). Then we do some practice exercises. 0:00 [Intro] 0:16

The Contrapositive and Proof by Contrapositive
The contrapositive is a powerful tool that can be used to prove various mathematical statements. It is most useful when a direct proof is awkward or impossible, and - if it can be used - is often a much more elegant method that employing proof by contradiction. #proof #contrapositive #proo
