A Level Further和IB Math AA都考,AP体系本身没有这个知识点,但学不学,暂时取决于precal老师想教些什么、教多少了。 先来看看复数极坐标形式的乘除法公式。 总结一下,复数极坐标形式乘除法:长度乘除、角度加减。这其实也可以在复平面 (complex plane) 中表示一下的。虽然,有可能是其他定理、公式用得太多,因为...

Operations in polar form: • 2) Find the reciprocal: 1/z –But we see there is a shortcut: –Take the reciprocal of the modulus, and negative θ –1/z = 1/r cis (-θ) Operations in polar form: • 3) Divide two complex numbers: z 1/ z 2 –Apply the two tricks we just...
The Polar Form of Complex Numbers A complex number is a number with an imaginary component. The imaginary component is represented by i, which is the square root of -1. A typical complex number in standard form looks like a + bi, where a and b are real numbers. The real part is a,...
Introduction to the Polar Form of Complex Numbers Complex numbers are commonly written inx+iyformat, whereistands for√(-1),xis thereal number partandyis theimaginarycoefficient. In mathematics, we can plot complex numbers in both theCartesian (x,y)andPolar (r,θ)coordinate systems. In this...
The notion of a phase or an argument of a complex number is what makes complex numbers have a flavor different from real numbers. To see what it is, letz = x + iybe a nonzero complex number. Then in terms of polar coordinates,zcan be identified as (r, θ), where\\[ r = |z|...

In order to work withcomplex numberswithoutdrawing vectors, we first need some kind of standard mathematical notation. There are two basic forms of complex number notation:polarandrectangular. Polar Form of a Complex Number The polar form is where a complex number is denoted by thelength(otherwise...
