[by commutativity and associativity of multiplication on real numbers]=(a^(k+1)*b^(k+1)).Therefore P(k+1):(ab)^(k+1)=(a^(k+1)*b^(k+1)Thus,P(1) is true and P(k+1) is true,whenever P(k) is true.Hence, by the principle of mathenmatical inductino,P(n) is true ...
TWO EXAMPLES OF PROOF BY MATHEMATICAL INDUCTION.DR. LOMONACOProposition: Use the principle of mathematical induction to prove that P (n) :nΣj=1j2 = n(n + 1) (2n + 1) 6 , for all integers n ^ 1. Proof (by weak induction): Basis Step: P(n) is true for n = 1, for:1Σj...
Use the principle of induction to show that ∑r=1nr2=n6(n+1)(2n+1). Method of Induction: Assume that the given statement P(n) is true for n=1. Now, assume that P(k) holds true. This suggests that the statement is true for the natural number...
Although I would prefer not to change the notations used by Lorentz, it appears important to me to use a different selection of symbols, for thereby certain homogeneity will appear from the very beginning. I shall denote the vector electric force by E, the magnetic induction by M, the electr...
In Section 1.2.1 we have discussed the puzzling nature of induction, which calls for well-posed explanations of the observed data. The parsimony principle (lex parsimoniae in Latin) is typically connected with classic Occam razor in philosophy, which states that entities should not be multiplied ...
The proof is based on mathematical induction over n. For n = 1, (30) which is fulfilled. For the induction step from n = l to n = l + 1, we assume that, for n = l, equation (29) is satisfied; then, (31) Thus, we only need to disc...

Show that in any set of n+1 positive integers not exceeding 2n, there must be two that are relatively prime. I tried mathematical induction, but I couldn't finish it. Say n=2, and we have n+1= 3 integers not exceeding 2n=4. It is 1, 2 and 3. It's okay for the base case....
A rival theory,finite additivity, requires less: The probability of a finite union of pairwise disjoint events is the sum of the individual probabilities, with no further restrictions placed on the probability of an infinite union of events. (When a probability is finitely but not countably add...
It is not hard to show that for any finite set of sentences {ψn}n<m in the language of set theory, one can force the Σ2-Potentialist Principle restricted to these sentences. Suppose this is the case for m, and let us prove it for m+1. First, using the induction hypothesis, ...
