纵观近年来全国高考数学试题,试题对“复数”内容考查的热点主要是复数的有关概念、复数的运算、几何意义、三角形及复数集上的方程等,其考查的要求都在《考试说明》中规定的“理解和掌握”层次上。题型一般是一道选择题和一道中档解答题,近年来高考试题对本章内容考查的深度呈稳中有降趋势。因此建议在本章的复习中,要紧紧抓住三条主线,以复数的概念为基础,复数的运算为中心,深刻理解复数的有关概念,熟练、准确掌握复数的运算。在复数的应用方面主要是复数集上的方程和复数运算的几何意义及|z_1—z_2|的几何意义的应用。对于在其它方面的应用(如复数
Looking at the mathematics questions in the National College Entrance Examination in recent years, the focus of the test questions on the content of the “plural” is mainly the concept of complex numbers, the calculation of complex numbers, the meaning of geometry, the equations on the set of triangles and complex numbers, and so on. The “comprehension and mastery” level specified in ". The question type is generally a multiple-choice question and a mid-range answer question. In recent years, the depth of examination questions on the high-test questions has been stable and there is a downward trend. Therefore, it is suggested that in the review of this chapter, we must firmly grasp the three main lines, based on the concept of plurals, and focus on the plural calculations, profoundly understand the concepts related to plural numbers, and skillfully grasp the arithmetic of complex numbers. The applications of complex numbers are mainly the geometric meaning of equations and complex operations on complex sets and the application of the geometric meaning of |z_1—z_2|. For other applications (such as plural
