一、命题热点与预测 复数在高中数学中自成体系,既有一定的独立性,又是解决其它学科知识的强有力的工具,更是高考的热门话题,热点内容有复数的有关概念,复数的向量表示,复数的代数形式、三角形式及其运算,在复数集中解方程等。考试说明对复数内容的具体要求为:(1)理解复数及其有关概念,掌握复数的代数、几何、三角表示及其转换。(2)掌握复数的运算法则,能正确进行复数的运算,并理解复数运算的几何意义。(3)掌握在复数集中解一元二次方程和二项方程的方法。从1990年以来的高考试题不难看出,复数题多为一大题和一小题的命题格局,其分值约占10%左右。
1. Propositional hotspots and predictive plurals are self-contained in high school mathematics. They have certain independence and they are powerful tools for solving knowledge in other disciplines. They are also hot topics in the college entrance examination. Hot topics include plural concepts. The vector representation, the algebraic form of the complex number, the triangular form and its operations, and the solution of the equations in the complex set. The specific requirements of the examination description for plural contents are: (1) To understand the plural and related concepts, to grasp the complex algebra, geometry, triangular representation and transformation of complex numbers. (2) Grasp the algorithm of the plural, can carry on the complex operation correctly, and understand the geometric meaning of the complex operation. (3) Master the method of solving a quadratic equation and a binomial equation in a complex number. It is not difficult to see from the high exam questions since 1990 that the plural questions are mostly propositional and propositional, with a score of about 10%.
