Witryna在数学中，虚数就是形如a+b*i的数，其中a,b是实数，且b≠0,i² = - 1。虚数这个名词是17世纪著名数学家笛卡尔创立，因为当时的观念认为这是真实不存在的数字。后来发现虚数a+b*i的实部a可对应平面上的横轴，虚部b可对应平面上的纵轴，这样虚数a+b*i可与平面内的点(a,b)对应。 WitrynaIt’s conventional in mathematics to use z to refer to a complex number, so I’ll continue on with that tradition. As always occurs with mathematical data types in R, you can convert other objects to class “complex” using. as.complex. : 1. 2. as.complex(-1) # [1] -1+0i.

WitrynaThis is an interesting question. The real numbers are a subset of the complex numbers, so zero is by definition a complex number ( and a real number, of course; just as a fraction is a rational number and a real number). If we define a pure real number as a complex number whose imaginary component is 0i, then 0 is a pure real number. Witrynawhere e is the base of the natural logarithm, i is the imaginary unit, and cos and sin are the trigonometric functions cosine and sine respectively. This complex exponential function is sometimes denoted cis x ("cosine plus i sine"). The formula is still valid if x is a complex number, and so some authors refer to the more general complex version as …
