WebbProving Inequalities Example: Use mathematical induction to prove that n <2n for all positive integers n. Solution: Let P(n) be the proposition that n <2n. •BASIS STEP: P(1) is true since 1<21=2. •INDUCTIVE STEP: Assume P(k) holds, i.e., k <2k, for an arbitrary positive integer k. •Must show that P(k +1)holds. Since by the inductive WebbExample 1: Proof By Contradiction That N Is Odd If N 2 Is Odd Remember that every whole number is either even or odd . So, if we can show that a whole number is not even, then it must be odd. If we can prove that N cannot be even when N 2 is odd, then we know it falls into the second category: the set of odd numbers. hinge pins screwfixWebbThe general approach is to study the properties of functions in the inequality using derivatives.

Solution: Let us assign the values as: a = 4 units, b = 7 units, and c = 5 units. Now let us apply the triangle inequality theorem: a + b > c ⇒ 4 + 7 > 5 ⇒ 11> 5 ……. (this is true) a + c > b
