SEM_012 - Linguistic Micro-Lectures: Equivalence (Logic)
What is a equivalence (in logic) and how is it used? Within less than two minutes Prof. Handke discusses and exemplifies the truth-conditions associated with this logical operator.

Equivalence Relations Definition and Examples
Please Subscribe here, thank you!!! https://goo.gl/JQ8Nys Equivalence Relations Definition and Examples. This video starts by defining a relation, reflexive relation, symmetric relation, transitive relation, and then an equivalence relation. Several examples are given.

This video focuses on how to write the converse of a conditional statement. In particular, this video shows how to flip the hypothesis and conclusion of a conditional statement. The concepts of truth value and logical equivalence are explored as well. Your feedback and requests are encour

Learn to show that the converse and inverse are logically equivalent statements
š Learn how to show that two statements are logically equivalent. Two statements are said to be logically equivalent if they contain the same logical content. i.e. if both statements convey the same meaning. A conditional statement and its contrapositive are logically equivalent. Also, the
From playlist Logically Equivalent Statements
Basic Methods: We define tautology and contradiction and consider the conditions of logical equivalence and implication. Examples include DeMorgan's Laws for logic, modus ponens, and the Law of the Excluded Middle. As a final note, we introduce the Substitution Rules.

3 Ways to Show a Logical Equivalence | Ex: DeMorgan's Laws
DeMorgan's Laws are two important logical equivalences. In introducing these laws, I talk about three different ways by which you can demonstrate a logical equivalences: There are truth tables, citing known laws, and testing for reasonableness. *******************************************
