Create a universal conditional statement in the domain of square roots of positive integers that is vacuously true. [A conditional is vacuously true if, and only if, the truth set of the hypothesis is empty.]
7 Show that the propositions (p Aq) and p V¬q are equivalent. logically
Using truth tables, or in any other way, prove that each of the following compound propositions is not a tautology. These implications are common logical fallacies (errors in reasoning) since the conclusion does not follow logically from the set of hypotheses. a. [(P⇒ Q) ^ Q] ⇒ P. b. [(PQ) ^ (~ P)] ⇒ (~ Q). For each one of the logical fallacies in part (iii) of this question give an example of a "real life" situation where such an error can occur.
Use truth table to establish the truth table of following 1)A conditional statement is not logically equivalent to its inverse
Consider the propositional language with only → and ⊥ as connectives. Is that lan- guage truth functionally complete?
Evaluate the proposition ∀∃y.P(x,y) ⇐⇒ ∃y.∀x.P(x,y) for an unknown predicate P. Could the statement be true? Must the statement be true for all P? Give a specific P (with domains for x and y) where it is either true or false. Prove that it is true for all P, or show a contradiction.
