一、虚数(Imaginary number)的定义 i2=−1 二、复数(Complex number)的定义 Cartesian form: z=a+bi ,其中a和b为实数,因此复数包含了实数和纯虚数; 实数部分 Re(z)=a ,虚数部分 Im(Z)=b (注意不是 bi); 三、复数的计算法则 若z1=a+bi, z2=c+di ,则 z1±z2=(a±c)+(b±d)i ,加...

of a Complex Number 10.3 Introduction In this Section we introduce a third way of expressing a complex number: the exponential form. We shall discover, through the use of the complex number notation, the intimate connection between the exponential function and the trigonometric functions. We shall...

A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, that satisfies the equation x2 = −1, that is, i2 = −1.[1] In this expression, a is ...
