# What is logical equivalence in discrete mathematics

• rg

In mathematics, an equivalence relation is a kind of binary relation that should be reflexive, symmetric and transitive. The well-known example of an equivalence relation is the "equal to (=)" relation. In other words, two elements of the given set are equivalent to each other if they belong to the same equivalence class.

One way of proving that two propositions are logically equivalent is to use a truth table. 2019. 2. 18. · tautology. The notation p ≡ q denotes that p and q are logically equivalent. Remark: The symbol ≡ is not a logical connective, and p ≡ q is not a compound proposition but rather is.

Logical Equivalence. We say two propositions p and q are logically equivalent if p ↔ q is a tautology. We denote this by . p ≡ q. The first method to show that two statements and p and q are equivalent is to build a truth table to to find the truth values of . p ↔ q. Since p ↔ q is true if and p and q have the same truth values, in this. 2021. 2. 19. · An argument is a set of statements, including premises and the conclusion.
