Jordan不等式的新型拓广及应用

摘要

By virtue of the decision system for polynomial and mathematical soft Maple, a new Jordantype inequality is established, and formed to obtain sharpening upper and lower bounds about Seiffert Mean and the extension for Kober inequality and Yangle inequality.%借助于多项式判别系统和maple数学软件，建立了Jordan不等式新的拓广形式，由此得到关于Seiffert平均的较强上下界，并推广了Kober不等式及杨乐不等式．
