复数问题的求解。首先要掌握好复数的各种表示形式及运算法则.其次对复数模、共轭、幅角的性质及几何意义也要正确把握.综合利用复数的性质及几何意义求解,常常能简捷、巧妙地解答问题.其中,转化的等价性要特别注意,我们从一道复数题的解法及反思来说明它. 问题1 已知复数z,满足|z|=1,且z1997 Solve the complex problem. First of all, we must grasp the various forms of expressions and algorithms. Secondly, we must correctly grasp the nature and geometric meaning of complex modes, conjugates, and arguments. Comprehensive use of the properties of complex numbers and the solution of geometric meanings can often be simplified and skillfully. Solve the problem. Among them, the equivalence of the transformation should pay special attention. We explain it from the solution and reflection of a plural problem. Problem 1 Known complex number z, satisfies |z|=1, and z1997
