WebJun 6, 2015 · To show that p ⇒ A by induction on the lenght of A is to use as n for induction the number of occurrences of connectives in it. For n = 0, the property clearly holds, because p ⇒ p. Then assume it true for a formula A n with n occurrences of conenctives and prove that p ⇒ A n ∧ p and p ⇒ A n ∨ p. – Mauro ALLEGRANZA Jun 6, … WebNov 15, 2024 · Solution: We will prove the result using the principle of mathematical induction. Step 1: For n = 1, we have 1 = 1, hence the given statement is true for n = 1. Step 2: Let us assume that the statement is true for n = k. Hence, 1 + 3 + 5 + ….. + ( 2 k − 1) = k 2 is true (it is an assumption).
