一、大学复变函数论中的复数内容大学复变函数论教材以新知识的形式呈现复数的相关概念(实数、虚数、纯虚数、复数、复数相等、共轭复数)、运算法则,接着引出复数域、复平面的概念,通过数形结合加以说明.在此基础上引入复数的模与辐角,这是整个复数部分的重点,由于学生之前未接触过,加之辐角的多值性,此部分又是难点.首先,给出了复数三角不等式,两点间的距离公式;其次给出辐角、主辐角的定义及辐角的运 First, the university complex function theory in the plural content University complex function theory textbook in the form of new knowledge to present complex related concepts (real number, imaginary number, pure imaginary number, complex number, complex number, conjugate complex number), algorithm, and then leads The concept of complex number domain and complex plane is described by the combination of number and shape. On this basis, the introduction of complex modulus and argument, which is the focus of the entire complex part, due to the students had not been exposed before, combined with the value of the argument, This part is also a difficult point.Firstly, given the complex trigonometric inequality, the distance between two points formula; followed by the definition of the argument of the main angle and the argument of the movement
