Triangle inequality for real numbers
WebThe triangle inequality for absolute value states that for all real numbers a and b, a + b < a + b . Use the recursive definition of summation, the triangle inequality, the definition of absolute value, and mathematical induction to prove that for all positive integers n. if a1,a2,...,an are real numbers, then. http://www.hep.upenn.edu/~johnda/Papers/RealNumbers.pdf

A norm is called non-Archimedean if it satis es the strong triangle inequality: kx+ yk maxfkxk;kykg: If a norm does not satisfy the strong triangle inequality it is said to be Archimedean. Remark 1.2. The strong triangle inequality clearly implies the triangle inequality.
