一个涉及三个三角形的三元二次型不等式

An Inequality of Quadratic Form of the Three Variables Referring to the Three Triangle

应用文献[1]的一个推论,建立了一个新的涉及三个三角形的三元二次型三角不等式,讨论了这一不等式的应用,解决了文献[1]中提出的一个猜想,提出了两个尚待解决的猜想。

Applying a corollary of the three sina inequality established by the author, a new triangle inequality of quadratic form of three variables veferring to three triangles is set up and its applications are discussed.Then one of the conjectures raised by the author in data [1] is solved.Finally,two conjectures yet robe solved are put forward.
