辅助元是为了解决某个问题而构造的一种数学形式(如线、角、平面、函数、方程、数列、圆等),用辅助元解题,体现了数学中类比,化归的思想,不仅使问题变得更直观明了,容易找到解决问题的思路和方法,同时也是一种富有创造性的解决问题的一种方法.一、构造辅助函数构造辅助函数是一种重要的解题思想方法.函数是整个高中数学的核心知识,它具有工具性和导向性.许多问题都可以通过巧妙地构造辅助函数,使得原本扑朔迷离的问题
Auxiliary element is a mathematical form (such as line, angle, plane, function, equation, series, circle, etc.) constructed to solve a certain problem. The auxiliary element solves the problem and embodies the idea of analogy and conversion in mathematics. Not only make the problem more intuitive and easy to find ideas and methods to solve the problem, but also a creative way to solve the problem.First, the construction of auxiliary functions Constructing auxiliary functions is an important way to solve problems. Function is the core knowledge of the whole high school mathematics, which is instrumental and oriented.Many problems can be cleverly constructed auxiliary functions, making the original complicated and confusing problem
