Suppose P, Q, and R are propositional forms. Explain why each is true.
(a) If P is equivalent to Q, then Q is equivalent to P.
(b) If P is equivalent to Q, and Q is equivalent to R, then P is equivalent to R.
(c) If P is equivalent to Q, then ∼P is equivalent to ∼Q.
(d) If Q is equivalent to R, then P ∧ Q is equivalent to P ∧ R.
(e) If Q is equivalent to R, then P ∨ Q is equivalent to P ∨ R.
