Concept of Quasi Sine of Volume angle of Simplex and It′s Application

Abstract:

      The main result of this paper is that the concept of quasi sine of space angle of n dimensional volumes in E^ｎ is builded and by it to correction of higher dimensional sine theorem and higher dimensional generalization of steiner theorem and the simply prove of inquality of tangential point. Some new inqualities of simplexes are push out by it.
