三角不等式,即在三角形中两边之和大于第三边,有时亦指用不等号连接的含有三角函数的式子(这里不作介绍)。三角不等式虽然简单,但却是平面几何不等式里最为基础的结论。
在[2]中尹景尧得出关于单纯形的一类三角不等式。
In [2], YIN Jing-rao gets the triangle inequality about simplex.
例如,R 2 的平方、二维向量的长度、三角不等式等都存在勾股定理。
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.
给出两个新的三角不等式,并将其应用于讨论角成等比的三角形形状。
