辐角是复数中个重要的概念,也一直是高考中频繁考查的内容之一,与代数、三角、几何都有着密切的联系,能比较好地考查学生的综合能力.求解时所用方法也很基本.常用的方法:(1)若θ是复数z=a+bi(a,6∈R)的辐角,则tanθ=b/a(a≠O),且θ与点(a,b)所在象限一致(或 Radiant angle is an important concept in the complex number, and it has always been one of the frequently examined contents in the college entrance examination. It has a close connection with algebra, triangles, and geometry. It can better examine students’ comprehensive ability. The method used for solving is also very Basic. Common methods: (1) If θ is the argument of the complex number z=a+bi(a, 6∈R), then tanθ=b/a(a≠O), and θ and point (a,b) Where the quadrant is consistent (or
