摘要
借助Huygens不等式、Jordan不等式等常用三角函数不等式,应用函数单调性和Cauchy微分中值定理导出若干新的三角函数不等式.
In this paper, by using the monotonicity several new inequalities for trigonometric functions are established of functions, Cauchy Mean Value Theorem, and some common inequalities for trigonometric functions such as Jordan inequality and Huygens inequality.
