The Inner Rdias of Univalence of Isosceles Trapezoid
Zongxin Yang · Journal of Jiangxi Normal University · 2008
In this paper,we take advantage of the method of David Calvis to proof that the inner radias of univalence of isosceles trapezoidwhose sides sequence is aaab and the minimun angle is kπ(where b=a+2acos kπ,0≤k≤1/3) to be 2k2.
