WebThe triangle inequality states that: For any triangle the length of any two sides of the triangle must be equal to or greater than the third side. Sometimes seen as: X+Y ≤ X + Y The inequality works not only if X and Y are both real numbers (scalars), but also if X and Y are vectors (of the same dimension). WebSome work is required to show the triangle inequality for the ￿ p-norm. Proposition 4.1. If E is a finite-dimensional vector space over R or C, for every real number p ≥ 1, the ￿ p-norm is indeed a norm.
