Prepositional Logic

Prepositional Logic. Lecture 5. Logical Equivalence. A stronger form of implication is expressed by the statement B is TRUE if and only if A is TRUE. This is usually written as A ?? B and is called logical equivalence The double arrow signifies that A ?? B is the same as A?B AND B?A
