In this video, the concept of reference formulae for logically true expressions in symbolic logic is explained. It discusses how certain logical formulas remain true under all possible interpretations, making them logically valid or tautologies. It explains that reference or standard formulas serve as the foundational patterns for all logically true expressions. By using these formulas, one can verify or derive the validity of complex propositions in formal logic. The video also emphasizes the importance of these reference formulas in understanding the structure of valid arguments and in constructing logical proofs. We use them especially in Normal functions to substitute one from the other.
