摘要
将连续函数的性质应用到不等式的解法中,使得解不等式的问题转化为解方程和判定函数值符号的问题,从而得到了解不等式的一种普遍的方法。
The essay applies the properties of continuous function to the solution of inequality. This changes the problem of solving inequality into one of solving equation and determining the sign of function value, thus obtains a universal solution of inequality.
