WebTo prove the triangle inequality, note that x+ y 2= (x+ y, x+ y) = (x, x) + 2 (x, y) + (y, y) x 2+ 2 x y + y 2 = ( x + y )2 Taking square roots gives the triangle inequality. The other two properties (2) and (3) of a norm are easy to prove. // Here is a way one can generate new norms from old. WebMar 24, 2024 · Triangle Inequality. Let and be vectors. Then the triangle inequality is given by. (1) Equivalently, for complex numbers and , (2) Geometrically, the right-hand part of the triangle inequality states that the sum of the lengths of any two sides of a triangle is greater than the length of the remaining side. A generalization is. WebThe triangle inequality theorem states that, in a triangle, the sum of lengths of any two sides is greater than the length of the third side. Suppose a, b and c are the lengths of the sides of a triangle, then, the sum of lengths of a and b is greater than the length c. Similarly, b + c > a, and a+ c > b. If, in any case, the given side lengths ... seeking christ in our christmas traditions
