摘要
应用一元高次方程根与系数的关系证明或者分析三角恒等式,是初等或者中等数学研究的热点课题。文中构建了5个一元高次方程,根据方程根与系数的关系,得到三角恒等式的一个来源。
Applying the relationship between roots and coefficients of first--order equation with higher degree to proving or analyzing of trigonometric identical equation has been a hot topic in primary or secondary mathematics. Five equations with higher degree of the first-order are formed to obtain a source of trigonometric identical equation according to the relationship between roots and coefficients.
