Problem 2: Use the logical equivalences established in Theorem 2.1.1 as well as the properties of conditional statements to prove that ~ (p → q) V (~p^ ~ q) =~ q . (Cite each equivalence used, and only use one at a time.) Problem 3: Show that the three statements below are all logically equivalent (using equivalences in the same way as Problem 2). (a) p → q V r (b) p ^ ~q →→ r (c) p ^ ~ r → q
