涉及复数模与辐角主值最值的问题是高考考点之一。本文就求复数辐角主值最值的几种方法举例说明. 一、数形结合法例1 已知z·z+(3+3~(1/2)i)z+(3-3~(1/2)i)z+9=0,求argz的最值及相应的复数.
The question concerning the maximum value of the main values of complex modes and arguments is one of the college entrance exams. In this paper, several methods for finding the maximum value of the principal values of complex arguments are illustrated. I. Numeral combination law example 1 Known z·z+(3+3~1/2)i)z+(3-3~(1/3) 2) i) z+9=0, find the argz value and the corresponding complex number.
