复数是高中数学中的重点内容之一.本文从笔者的教学实际经验出发,例举复数的形式和解题思路,有助提升教学效果的一些有益尝试和有效策略.一、复平面上的轨迹问题例1已知a∈R,则复数z=(a~2-2a+4)-(a~2-2a+2)i所对应的点在第几象限,复数z对应点的轨迹是什么?分析根据复数与复平面上点的对应关系可以
Pluralism is one of the key contents in high school mathematics.This article starts from the author’s teaching experience and gives examples of the plural forms and solutions to problems that will help to improve the teaching effectiveness of some beneficial attempts and effective strategies.A complex plane trajectory Problem 1 Given that a∈R, then the complex number z = (a ~ 2-2a + 4) - (a ~ 2-2a + 2) i in the first quadrant, what is the trajectory of the complex point z Analyze the correspondence between complex points and points on the complex plane
