WebJul 7, 2024 · Induction can also be used to prove inequalities, which often require more work to finish. Example 3.5.2 Prove that 1 + 1 4 + ⋯ + 1 n2 ≤ 2 − 1 n for all positive integers n. Draft. In the inductive hypothesis, we assume that the inequality holds when n = k for some integer k ≥ 1. This means we assume k ∑ i = 1 1 i2 ≤ 2 − 1 k. WebJan 12, 2024 · Written mathematically we are trying to prove: n ----- \ / 2^r = 2^ (n+1)-1 ----- r=0 Induction has three steps : 1) Prove it's true for one value. 2) Prove it's true for the next value. The way we do step 2 is assume it's true for some arbitrary value (in this case k). WebSep 1, 2024 · For the induction step, we will use Bernoulli's inequality (BI) in the form ( 1 + x) n ≥ 1 + n x for integer n ≥ 1 , real x > − 1 with equality only when x = 0 or n = 1. Proof of BI. True for n = 1. If n ≥ 1 , then ( 1 + x) n + 1 = ( 1 + x) n ( 1 + x) ≥ ( 1 + n x) ( 1 + x) = 1 + ( n + 1) x + n x 2 ≥ 1 + ( n + 1) x with equality only when x = 0. hair follicle cycling
