中文摘要:
      本文给出余弦函数的两个公理:(?)得到公理1,2等价于我们熟知的余弦函数定义域幂级数定义.(见Dr.Konrad Knopp)heory and application of Inpinitc sehies(Frist English Edition1928;Second English Edi-tion1951)).

      In this paper, two axioms for cosine function are given and the well-known definitions defined by power series as well as by the arc length on a unit circle have been obtained. Obviously the latter implies both axioms. Thus the two axioms given do constitute a characterization for the cosine function.
