Conditional Theorem (p → q) ⇐⇒ (¬q → ¬p) ⇐⇒ (¬p ∨ q) Proof. The first formal equivalence has been proven in the previous session, so we just have to look at the truth tables of p → q and ¬p ∨ q. p 0 0 1 1
q 0 1 0 1
p→q 1 1 0 1
¬p 1 1 0 0
¬p ∨ q 1 1 0 1

Conditional Theorem (p → q) ⇐⇒ (¬q → ¬p) ⇐⇒ (¬p ∨ q) Proof. The first formal equivalence has been proven in the previous session, so we just have to look at the truth tables of p → q and ¬p ∨ q. p 0 0 1 1
q 0 1 0 1
p→q 1 1 0 1
¬p 1 1 0 0
¬p ∨ q 1 1 0 1
As p → q and ¬p ∨ q have the same truth table, they are formally equivalent.

Biconditional Theorem (p ↔ q) ⇐⇒ (¬q ↔ ¬p) Proof. Once again, we just have to look at the truth tables of the two propositions. p 0 0 1 1
q 0 1 0 1
p↔q 1 0 0 1
¬p 1 1 0 0
¬q 1 0 1 0
¬p ↔ ¬q 1 0 0 1
