Note of the Cauchy Inequality
摘要
Abstract
By using the Pythagorean theorem of vectors, the Cauchy inequality and the triangle inequality are proved and the relationship of these two inequalities are discussed. The Cauchy inequality is proved by using the triangle inequality. Moreover, an ignored detail in the name of the Cauchy inequality is pointed out.关键词
