This sort of logical proof can easily be written in straight term mode though example (p q r Prop) (p ∨ q) ∧ (p ∨ r) → p ∨ (q ∧ r) = λ hpq, hpr , orelim hpq orinl $ λ hq, orelim hpr orinl $ λ hr, orinr hq, hr The "duplication" now is just the fact that the function orinl shows up twice My feeling is that because p但它们是有联系的， p 和 q 是语法等价的，当且仅当 p ↔ q 是一个 定理 ，而 p 和 q 是语义等价的， 当且仅当 p ↔ q 是 重言式 。 逻辑等价有时表示为 p ≡ q 或 p ⇔ q 。 但是，后者记号也用于实质等价。 逻辑等价公式 包括 蕴涵 的逻辑等价： p→q≡﹁p∨q p→q≡﹁q→﹁p p∨q≡﹁p→q p∧q≡﹁ (p→﹁q) ﹁ (p→q)≡p∧﹁q (p→q)∧ (p→r)≡p→ (q∧r) (p→q)∨ (p→r)≡p→ (q∨r) (p→r)∧ (q→r)≡ (p∨q)→r (p→r)∨Answer (1 of 2) Question originally answered What is the truth table for (p>q) ^ (q>r)> (p>r)?

As (q ^ r) is common to both of these expressions, you are effectively saying that ~p ^ (~q ^ r) v (p ^ r) ≡ ~p ^ (p ^ r) v (~q ^ r) which is NOT the caseExample 213 p_q!r Discussion One of the important techniques used in proving theorems is to replace, or substitute, one proposition by another one that is equivalent to it In this section we will list some of the basic propositional equivalences and show how they can be 1 I came across this problem, it asks to use logical equivalences (see image), show that ( p → r) ∨ ( q → r) logically equivalent to the statement ( p ∧ q) → r (aka definition of biconditional) After apply p → q ≡ ¬ p ∨ q, I can't go any further can anyone show me any steps further?
