Discrete Mathematics class 12 TN Stateboard | Prove logical equivalence WITHOUT truthtable | Ex 12.2

In this video, we discuss the questions from the chapter discrete mathematics - from 12th grade, TN stateboard. The questions are from exercise 12.2 - question numbers 12 and 14, and also example 12.19. The questions are discussed in Tamil. As we are not using the truth table, the questions are solved using the important laws 1. Idempotent Laws: p ∨ p ≡ p p ∧ p ≡ p 2. Commutative Laws: p ∨ q ≡ q ∨ p p ∧ q ≡ q ∧ p 3. Associative Laws: (p ∨ q) ∨ r ≡ p ∨ (q ∨ r) (p ∧ q) ∧ r ≡ p ∧ (q ∧ r) 4. Identity Laws: p ∨ F ≡ p p ∧ T ≡ p 5. Complement Laws: p ∨ ¬p ≡ T p ∧ ¬p ≡ F 6. Involution Law (Double Negation): ¬(¬p) ≡ p 7. De Morgan’s Laws: ¬(p ∨ q) ≡ ¬p ∧ ¬q ¬(p ∧ q) ≡ ¬p ∨ ¬q 8. Absorption Laws: p ∨ (p ∧ q) ≡ p p ∧ (p ∨ q) ≡ p Note: 'T' stands for True, 'F' stands for False, '∨' is OR, '∧' is AND, and '¬' is NOT About us: We at SD Institute offer online coaching to students of CBSE from Class 9 to 12.
