How can we make a truth table ?
2. Use truth tables to show that the following statements are logically equivalent: (a) PV (QAR) = (PVQ) ^ (PVR) *The examples, section numbers are from Richard Hammack's "Book of Proof". (b) P⇒Q=(-P) VQ Additional Problems 1. Make a truth table for (PV-P) VQ. 2. Show the logical equivalence: (PA(-PVQ))--PV-Q. H
