Real number, in mathematics, a quantity that can be expressed as an infinite decimal expansion. The real numbers include the positive and negative integers and the fractions made from those integers (or rational numbers) and also the irrational numbers.

第一章的答案,这一章的习题比较简单,个人认为6,7,8,20是好题。
之前常见到的cosine与sine讯号进行傅立叶,转换过程这边就不细说,但大概都有印象cos(wt)或sin(wt)都会看到转出 -w负频率的成分,而且在数学计算上面频谱为复数Complex number形式 (a+bi)出现,这也是一个在学习工作工程困扰我的过程,因为一般频谱分析仪都是量测大小,看不到所谓的负频成分与复数形式,那种看不到但感...
Estimates for the number of sums and products and for exponential sums over subgrups in finite fields of prime order We give a simple argument that for any finite set of complex numbers $A$, the size of the the sum-set, $A+A$, or the product-set, $A\\cdot A$, is always la.....
The arguments in CSub can be either complex numbers or real numbers: e.g. CSub(B3:C3, 3) or CSub(F3, B5:C5). The first argument in CDiv can be a complex or real number: e.g. CDiv(1,B5:C5). Multiplication of a complex number z by a real number a can be accomplished by ...
Let a and b be real numbers with a≠ b. Let z=x+iy be a complex number such that|z-a|^2-|z-b|^2=1 .Prove that x = _- + 相关知识点: 试题来源: 解析 |x+iy-a|^2-|x+iy-b|^2=1 |(x-a)+iy^2-|(x-b)+iy^2=1 (x-a)^2+y^2-(x-b)^2+y^2=1 (x-a)^...
where a and b are real numbers and i2=-1( or equivalently, . A complex number is often denoted by a single letter,usually z,we write z=a+bi, where a=Rez(read:"the real part of z") and b=Im z ("the imaginary part of z").If b=0,the number is real;if a=0,it is imagi...
