1955年10月号数学通报发表了王友鋆先生“谈倒数方程”一文.他对倒数方程的定义是这样下的: 定义如一方程的根两两互为倒数或两两互为负倒数,则这方程就叫倒数方程. 这样从某一方程的根作为出发点来定义倒数方程.这种定义法,我是不大同意的. 因为我们学倒数方程的目的是利用比较固定而方便的方法来解特殊的一元高次方程(一 In October 1955, the Mathematics Bulletin published the article “On the reciprocal equation” by Mr. Wang Youzhao. His definition of the reciprocal equation is as follows: Definition: If the root of an equation is reciprocal, or if the two are negative reciprocal, then the equation It’s called the reciprocal equation. This defines the reciprocal equation from the root of an equation as a starting point. I don’t agree with this definition method because the purpose of our reciprocal equation is to use a more fixed and convenient method to solve special equations. One-dimensional high-order equation (a
