triangle inequality

基本解釋

To establish a triangle inequality with exponent parameter.
建立一個(gè)含指數(shù)參數(shù)的三角形不等式。
You can say that the proof uses nothing beyond elementary matrix theory, repeated use of the triangle inequality, and the pigeonhole principle.
你可以簡(jiǎn)要地說(shuō)其實(shí)證明就是初等矩陣?yán)碚?，三角不等式和鴿籠原理的運(yùn)用。
For instance, it's also the square of the Euclidean norm on R2, the length of a two-dimensional vector, a part of the triangle inequality, and quite a bit more.
例如，R 2 的平方、二維向量的長(zhǎng)度、三角不等式等都存在勾股定理。
